Why does God want us to verbalize our confession?
God expects believers to communicate their confession not only to Himself but also to others, because He is a communicator and looks for verbalization rather than mere mental assent. Scripture ties salvation to confessing with the mouth, so saying aloud that one is a sinner and trusting God makes the inward reality outward and testifies before others.
Les teaches from Romans 10:9-13 that God expects you to communicate this confession not only to Himself but also to others. He explains that God is a communicator and expects us to verbalize these things. Too many people have only had a mental ascent, saying, “Well, yeah, I believe in God,” but that is not what God is looking for. God is looking for a verbalization of all these various steps, such as telling God out loud, “Lord, I’m a sinner,” recognizing from Scripture that you are a sinner. This fits the broader context where sin abounded but grace did much more abound, and God is able to reach below the vilest sinner, lift him up, and make him a saint. Paul refers to his Gospel as the Gospel of the Grace of God.
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
