Your desire for a wise and understanding heart to be a faithful steward is itself pleasing to God, and He delights to give wisdom to those who ask Him for it. Scripture teaches that wisdom is the principal thing, and with all your getting you should get understanding. It is more precious than silver or gold or rubies, it prolongs life, and its ways are pleasantness and peace. The beginning of that wisdom is the fear of the Lord, and to depart from evil is understanding.
God gives this wisdom not through human cleverness, which is foolishness to Him and comes to nothing, but as you receive His words, hide His commandments with you, incline your ear to wisdom and apply your heart to understanding, and cry out for knowledge. When wisdom enters your heart and knowledge becomes pleasant to your soul, it guards your path and makes you discreet. Write His mercy and truth on the table of your heart, treat wisdom as a close companion and understanding as family, and trust in the Lord with all your heart rather than leaning on your own understanding. In Christ Himself are hidden all the treasures of wisdom and knowledge, and by wisdom the Lord founded the earth and by understanding He established the heavens. He promises to pour out His Spirit of wisdom and understanding on those who seek Him early and seek Him with all their heart, pouring out their soul before Him in prayer and learning effectively in His Word. As you do, you will find favor and good understanding in the sight of God and man.
Your prayer from Proverbs 13:20 is a good and biblical prayer. He who walks with the wise will become wise. Ask the Lord to place wise, godly people around you, and to help you to walk closely with them, listening, learning, and growing in His Word day by day.
I join you in prayer for healing, asking our Heavenly Father in the name of Jesus Christ to touch your body according to His mercy and power. I pray for your teeth and especially the upper wisdom tooth on the right, for your eyes, for the entire left leg and the left side of the pelvis, for the area in the upper left thigh, for the area on the abdomen, and for your stomach, intestines and entire gastrointestinal tract. May the Lord bring complete healing, relieve pain, restore strength and health, and grant wisdom to any who care for you. A joyful heart does good like medicine, and our God is able to heal and to sustain.
May the Lord help you to seek Him with your whole heart, to pour out your soul before Him, and to grow in the knowledge of His Word. May He grant you a wise and understanding heart to steward well all that He has entrusted to you, and may you walk in the path of the righteous, guided by His counsel and strength. Those who love wisdom and seek it will find it, and He will direct your steps.
