Matthew 12:35 - "A good man out of the good treasure of the heart bringeth forth good things."
Who did Jesus say brings it forth?
The good man from the good deposit of his heart brings it forth.
What you deposit in your heart is what will come forth, for out of the abundance of the heart, the mouth speaks.
What's abundantly in your heart will always get in your mouth.
Then on the other hand what's abundantly in your mouth will also get in your heart.
In other words, you establish things in your heart by "saying" them with your mouth, and the cycle starts all over again.
James 1:26 - "If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain."
If you are not a doer of the Word, no on has to deceive you, because you are are deceived already.
If you don't bridle your tongue--it will deceive your heart.
You will sow the wrong words, and the seed you sow will produce after its kind. Many people wonder why things turn out the way the do not realizing their tongue deceived their heart, and their heart brought forth fruit of itself.
In Romans 10:6-8 Paul tells us, "the righteousness which is of faith speaketh...the word is nigh thee, even in thy mouth and in thy heart."
Notice it's in your mouth first, then in your heart.
Jesus confirms this in Luke 17:5,6. When the apostles asked Him to increase their faith, His answer was: "If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root and be thou planted in the sea; and it should obey you."
He didn't say a thing about giving them more faith. He told them to plant their faith by "saying", and it would produce.
I SPEAK GODS PROMISES INTO MY HEART EVERY DAY.
I PLANT FAITH AS A SEED BY RELEASING IT IN WORDS.
I SPEAK ONLY THOSE THINGS THAT I WANT TO GROW IN MY LIFE.
