“Keep thy heart with all diligence; for out of it are the issues of life.” Proverbs 4:23
Why are there so many … who are spiritual failures, who have unsymmetrical characters? It is because they did not, when they knew the truth, and do not now, begin to practice the truth as it is in Jesus. They do not let Him take away their faulty attributes of character…. He whose conversion is righteous carries righteous principles into all his life practices. He only is well grounded in the faith who lives by every word that proceedeth from the mouth of God.
