Every believer is making two professions of faith

Tit 1:16  They profess to know God, but they deny him by their works.

We see in this above verse this:

Our actions also do the confessing.

Our lips confess the Lord Jesus, and make profession that we are Christians.

But our actions also make a profession. Our actions are speaking. They are saying a word. They are screaming "I do not know Jesus Christ"!

How do we respond to the Gospel? By our lips? Yes. For Paul says in Romans, whoever will call upon the name of Christ will be saved.

But we also respond to the Gospel by our actions, by our hands, feet, lips and our bodies. By our works, we either respond to Him, or we deny Him.

So there are two confessions going on: one by our lips, and one by our actions.

If the actions do not match up, whatever we say with our lips shall be silenced, made to be worth nothing. There is nothing worse than hypocrisy.

This indeed is the message of James, who admonishes us to keep silent, but rather show good works:
Jas 3:2  For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body.
Jas 3:13  Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom.

And again he says to the one who makes a profession of faith with his lips but not with their actions:
Jas 2:14  What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him?

Jas 2:18  But someone will say, "You have faith and I have works." Show me your faith apart from your works, and I will show you my faith by my works.
Jas 2:19  You believe that God is one; you do well. Even the demons believe—and shudder!

James in v18 asks, "Show me your faith apart from works". Now how DOES a person show faith apart from works?:

By boasting with his lips: "I AM a Christian! I AM saved! God loves me!"

Yet his actions do not show that He is a believer. 

It is our actions that make all the difference. It is by our actions we show that we are a believer. And then it is accompanied by words.

It was Jesus' voluntary death and resurrection that spoke more words than anything ethical or moral that He said. By His death, He achieved more than Mohammed or Buddha who were nothing but lips. 

It was the works of love for His people that was heard by heard, and seen by us, and changed us.

Let us unite our profession of our lips with the profession of our bodies, that what we say will be what we are, and what we are, what we say.
