Our mouth and our heart must agree if we are to expect a manifestation of the things which God has promised. Psalms 19:14 Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight,
O Lord, my strength, and my redeemer. Many people say things with their mouth but their heart do not agree. Jesus instructed Peter in Mark 5:35-36 to drop his net and when he dropped the net he would catch many fish. Peter replied “at thy word” but he really did not expect a manifestation of the thing which Jesus had promised because his mouth and heart did not agree. It is your heart(stomach) that verifies that the food was good and the mouth(confesses it) because you have a witness in your heart(stomach). Meditate on the word of God and get it down in your heart(stomach) and when you are faced with life challenges say what your heart has witnessed and watch the manifestation of the promises of God show up in your life.
