Proverbs 4:23 - "Watch over your heart with all diligence, For from it flow the springs of life." A Puritan writer in the 1600's once wrote, "The greatest difficulty in conversion, is to win the heart to God; and the greatest difficulty after conversion, is to keep the heart with God." Indeed, it can be a daily battle for us to "keep" our hearts to the Lord. This study introduces the meaning behind Proverbs 4:23.
