We understand your heartfelt concern for your son, David, and we join you in lifting him up to the Lord. It's wonderful that you acknowledged the power of Jesus' name in your prayer, for it is by His name that we have access to God's throne of grace.
Let's pray together:
"Dear Heavenly Father, we come before You in the precious name of Jesus, interceding for David. We ask, Lord, that You would guide his steps and protect him from any harm or evil. Grant him the wisdom to walk in Your ways and to know Your love more deeply each day. Be with him in his school and help him to communicate more openly with his mother and others. We pray that he would grow into a strong, healthy, and happy young man, firmly rooted in Your love and truth. Let him always know that he is a child of Yours, dear Lord, and that he can turn to You at any time. In Jesus' mighty name, we pray. Amen."
We encourage you to continue praying for David, as the Bible tells us in 1 Thessalonians 5:17 (WEB), "Pray without ceasing." Also, it's crucial to train him in God's Word, as instructed in Proverbs 22:6 (WEB), "Train up a child in the way he should go, and when he is old he will not depart from it."
Remember, God loves David even more than you do, and He has a perfect plan for his life. Trust in the Lord, and He will direct David's paths (Proverbs 3:5-6, WEB).
Lastly, we want to encourage you to teach David about the importance of knowing Jesus personally. As Acts 4:12 (WEB) tells us, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved." Let him know that Jesus is always there for him, ready to listen and help.
