The Law leads us to Jesus Christ

Numbers 33:15 (KJV)
And they departed from Rephidim, and pitched in the wilderness of Sinai.

Sinai was where God gave the Ten Commandments and entered into a covenant of law with Israel. God spoke from heaven from the mount His Law of Love, of loving God and of loving people. Moses read the book of the covenant in which he wrote His laws, and sprinkled the blood of the covenant upon Israel, which signified that they were bought with the blood from among the nations to be a kingdom of priesthood and a holy nation. Moses then went up the mount for 40 days, during which God described and showed to him of the tabernacle of God and the things in it, with the Ark, table for shewbread, the lamp-stand and other instruments. God explained to Moses of Aaron's priesthood, of what he ought to wear, and how they are to be consecrated and ordained.

But while Moses was away forty days to receive these laws and statutes, Aaron and the people were already breaking the commandments that they swore they would obey only a while ago. God was angry with these people, and desired to destroy them all, but Moses interceded for them, and God preserved them. Afterward God desired not to go with them to the promised land, but desired to send with them an angel instead, for they had provoked His holiness and His anger. But Moses sought God's face and His glory with all his heart, and interceded for God's presence to go with them. God heard Moses, and He renewed the covenant with them. Moses built the tabernacle as God had commanded him, with the Ark and all its instruments, and the glory of the Lord filled the tabernacle. And God was with them throughout their journeys.

What can we learn from Sinai? We learn first of all why God gave the Law to Israel. Did God give the Law for Israel so that they would keep it and become righteous by it? No. Yes, God did say to Israel, "Do these things", and that's what God would have liked to see, but that was not God's main purpose for giving the Law. How do we know this? See how quickly they started breaking the commandments as soon as they received it, as soon as Moses had ascended to the mount for forty days. Have a look at how much more the hostility of their sins increased after they heard the law. The more they heard the law, the more lawless Israel became. And their lawless increased throughout their history until they killed God's only begotten Son who had visited them.

Bible says the law was not introduced to make anyone justified, but rather, to show that we are already condemned:
Romans 3:19 (KJV)
Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
The law was introduced to show that we are guilty before God. See how specific the sins mentioned in the Ten Commandments are: idolatry, blasphemy, theft, murder, adultery, covetousness, etc. These are 10 major sins of mankind. Before we knew these commandments, we committed these things, in both heart and deed, not realizing these offended God. But when we read the bible, or heard from a preacher, we realized that these were indeed sin.
Romans 3:20 (KJV)
Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
But this knowledge of sin through the law did not stop our sins, contrary to what we imagined. We thought that we were pretty good and moral people, and by keeping these commandments we could make ourselves even better. But on the contrary, the law actually provoked our sin, and made us even more sinful. The law made our sin to increase, and made it abound. And indeed, that was the very purpose of the law:
Romans 5:20 (KJV)
Moreover the law entered, that the offence might abound.
So then, the law was introduced to show that we are deserving of eternal punishment, to make us to know what sin is, and that our sins may increase. Was it because the law itself was sinful? Was God evil for doing this so that our sins may increase? By no means. On the contrary, it experimentally showed how evil, wicked, depraved, sinful and fallen man is. God had given His people a perfectly good law and rules to follow, but that perfectly good thing was to them an occasion for them to sin the more. The law showed how hostile their minds were to God's ways. It showed them that they were not just sinful, but "exceedingly sinful":
Romans 7:13 (KJV)
Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
We are evil. When God tells us to not do something, we are a people that go out of our way to do that which God hates. When God says "do this", we won't even move one inch, we won't even lift one finger to do that which God has commanded. Yet we offend God even more when we love to obey other people but God. We are hostile to Him, not because there was a point in our lives when we became sinful, but because we were born evil. We are all children of Adam and Eve's disobedience, and their sin is in our DNA. We are twisted on the inside and we love evil. We hate God more than anything and we love opposing God above all things. We are the children of wrath, we are all as an unclean thing before His eyes. We are all an abomination, and God introduced the Law to us so that WE ourselves may see this truth also.

But is that the only reason why God gave the Law? By no means. God gave us the Law that we may go to Jesus Christ, our only hope:
Galatians 3:23-24 (KJV)
But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed. [24] Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
The Law leads us to put our faith alone in Jesus Christ. There is no other hope. God gave us the Law through Moses, that we may flee to His own Son for safety. There is a Day coming, when the wrath of God shall be poured out upon all nations for our lawlessnesses. How shall we escape this coming wrath of God? By taking refuge in Jesus Christ. He is the one who bore our sins on that tree. We must take refuge under His shed blood for cover. God has not ordained any other method of Salvation, for no one else died under God's law for us. Jesus Christ is the one who prayed and interceded for us that those who believe in Him may be saved. Jesus Christ is the one who intercedes for us day and night in heaven, that God's wrath may not fall upon us. God's wrath fell upon Christ. God abandoned Christ on that tree momentarily, that He may be with us forever. Jesus Christ was the tabernacle that was raised after three days that God's glory may be with all who would put their trust in Him.

Jesus Christ is the one who became our righteousness apart from the law. By Him we are justified - accounted to be righteous in God's eyes by faith. By Him our sins are covered by His blood which was paid for transgressions. By faith in this Gospel the power of sin is broken in our lives, as we realize what wonderful love that God has shown for us through Jesus Christ. Knowing that Jesus Christ took all our guilt and condemnation and crucified them with Him, it brings a godly gratitude and joy in our hearts that causes us to sin less. When we realize that though the law increased our sins, but that the grace of God also increased to overcome these sins by the power of His cross, we are speechless and we give Him glory. Now we keep the law, not because we want to be righteous, but because we're thankful that God saved us from the bondage of sin, condemnation and death.

We also learn from Sinai that we ought to seek God's face. God had been displeased with Israel's wickedness, but Moses sook God's glory and His face. Moses was not content to go with an angel to the promised land. He wanted the presence of God. Moses was not content of being just saved, but he wanted God. He loved God and wanted His glory. He did not just want knowledge of the things of God, but He wanted to know God. He wanted to know who God really was. He wanted to see God, if he could, not out of curiosity, but out of love and adoration to God. And God showed Himself to Moses:
Exodus 34:5-7 (KJV)
And the Lord descended in the cloud, and stood with him there, and proclaimed the name of the Lord . [6] And the Lord passed by before him, and proclaimed, The Lord , The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth, [7] Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty ; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.
And who is this Lord God, the God who is so gracious, merciful and forgiving, yet who is full of goodness and truth and never compromises His justice, and punishes the guilty unto the fourth generation? This God revealed Himself to us by sending His own Son, and fulfilling this Name on the cross of Calvary. God hallowed His name by killing His own as punishment for our sins, that He may show that He is both loving and righteous at the same time, as His Name suggests. This was the glory of God that God manifested through His Son, the Mystery of God revealed:
2 Corinthians 4:6 (KJV)
For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
Jesus Christ is the face of God that we should seek. Moses needed to veil his face when he came down after hearing God's name, but Jesus Christ does not hide His glory to those who believe. The veil has been forever removed, and we by faith are beholding God's glory in the face of Jesus Christ every day, being changed from glory to glory.

We remember how Moses, after hearing God's Name, he gathered up courage to ask God for grace:
Exodus 34:9 (KJV)
And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.
When we behold the glory of God in Jesus Christ, we also can have the courage to ask God for His grace and forgiveness. When we behold God's glory in His Gospel, we have the boldness to enter into the throne of His grace. That all men might see and know who God really is! Then they would run to His arms and not away from His arms. That all men might see that God is love! Let us ask for His mercy and His grace everyday, both for ourselves and for others. God will hear from heaven, and by His lovingkindness He will go with us and not forsake us. He will do this for His great Name's, and for Christ's sake. Let us seek Him:
Amos 5:4 (KJV)
For thus saith the Lord unto the house of Israel, Seek ye me, and ye shall live:
