You harvest what you plant. Pumpkins seed produce pumpkins. Squash plants produce squash. That is why you must ask the Lord to plant within you a clean heart, so that your life will produce clean thoughts, actions, and motives. The bad desires and thoughts that remain are evidence that some bad seeds have also been planted and you need to do some weeding. Complete renewal is not yet accomplished. None of us will be entirely pure in this life, but purity of mind and heart is one of the most worthy goals to pursue. Is it your goal? How will you strive to reach your goals inside and out?
I am sure that God, who began the good work within you, will continue his work until it is finally finished on that day when Christ Jesus comes back again. Philippians 1: 6
Create in me a clean heart, O God. Renew a right spirit within me. Psalm 51:10
