‘Now, faith is the substance of things hoped for; the evidence of things not seen.’ Hebrews 11:1
How many times have you made statements about God seeing your heart and the faith in it, but your actions totally negate that? Is faith really just a thing of the heart? No, it’s more than that.
For every miracle that Jesus performed, He took steps according to his faith and a manifestation was seen on the outside. During the feeding of the five thousand, he gave thanks for the bread, broke it and asked that it be shared among the people. At the tomb of Lazarus, he did not stay back where he was, believing in His heart that Lazarus would walk out of the tomb, alive. He went there, asked that the stone be rolled away and commanded Lazarus to ‘Come forth’.
So you’re probably thinking that that is Jesus. How about Peter? He wanted to walk on water, he believed he could, but he didn’t leave the faith in his heart, he stepped out of the boat and walked. When (together with John) he was going to heal the lame man at the Beautiful Gate, he did not just believe in his heart that this man would be healed and walked away. He spoke to him and pulled him up to walk, and the man did.
Your faith should affect your words and your actions too. That is living faith. Faith that is not accompanied with actions is just a dream, a wish and it will not yield any results.
So also faith, if it does not have works (deeds and actions of obedience to back it up), by itself is destitute of power (inoperative, dead). James 2:17 (AMP)
It is not enough to simply believe in your heart, confessing with your mouth is also necessary. Jesus in Mark 11:23 laid emphasis on the word ‘say’. This shows that you can school your heart to believe what you want it to through your words. Don’t let the doubt that seems to be finding space in your heart, find its way to your mouth.
Believe with your heart, confess with your mouth and live out your faith.
