Whatsoever a man has in his heart, good or evil, he speaks with his mouth and does in his life.
A good man from the good treasure of his heart speaks good things and brings forth good things.
If a man's heart is evil he can only speak evil and do evil.
Evil words and evil works always spring forth from a heart filled with sin and corruption.
Good words and good works can only flow like living water from a heart made pure by the purifying power of Jesus Christ.
As the scripture has said, All who believe on me out of his heart shall flow rivers of living water.
Jesus said, If anyone thirst, let him come to Me and drink. He who believes in me, as the Scripture says, from within him there shall flow rivers of living water.
An evil spring brings forth poison water, a good spring good
water.
