"Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful. But his delight is in the law of the LORD; and in his law doth he meditate day and night. And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper." Psalm 1:1-3
When you read, meditate and study God's Word, you are like a tree planted by living waters. God's fruit (love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance) will flow out of your life effortlessly. Your leaf (youth, health) will not wither. If you say, but I am reading God's Word, but I am still sick, then I say increase the dose! In Proverbs 4, it says his Word is health to all your flesh. In the Hebrew, health here literally means medicine. All you need is either more medicine or stronger medicine, so read more of God's Word. Study more. Meditate more. You will bring forth fruit in due time!
