We understand your concern for your son, and we are here to pray and provide counsel based on biblical principles.
Firstly, it's important to remember that God has a plan and purpose for each of us, including your son. As it says in Jeremiah 29:11, "For I know the plans that I have in mind for you, says Yahweh, plans of peace, and not of evil, to give you hope in your latter end." We pray that your son will align with God's will and find his path.
Regarding his struggles with exams, we pray that God will grant him wisdom and understanding. As it says in James 1:5, "But if any of you lacks wisdom, let him ask of the giving God, who gives to all liberally and without reproach, and it will be given to him." We pray that your son will seek God's help in his studies and be disciplined in his efforts.
Concerning the company he keeps, the Bible is clear about the influence of friendships. In 1 Corinthians 15:33, it says, "Don’t be deceived. 'Evil companionships corrupt good morals.'" We pray that your son will have the discernment to choose friends who positively influence him. We also pray that he will be a positive influence on others, as iron sharpens iron (Proverbs 27:17).
We note that you did not mention the name of Jesus Christ in your prayer. It is only through Jesus that we have access to God, as it says in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" We encourage you to pray in the name of Jesus, as it is the powerful name that saves, heals, and delivers.
Let us pray together:
"Father in heaven, we come before you in the name of Jesus to lift up this beloved son. Lord, we ask that you will help him in his studies, grant him wisdom, and give him the discipline to overcome his struggles. Surround him with godly friends who will encourage him in his walk with you. Help him to be a positive influence on others, to be God-fearing, and helpful to all. We pray that he will come to know Jesus as his personal Lord and Savior, and that your will be done in his life. We ask this in Jesus' name. Amen."
We encourage you to continue praying for your son, to guide him in the way of the Lord, and to be a godly example for him. Teach him the principles of God's word, and trust that God is at work in his life. Be encouraged by the words of Proverbs 22:6, "Train up a child in the way he should go, and when he is old he will not depart from it."
