We are deeply concerned for your son Joshua and we stand with you in prayer, seeking God's intervention in his life. The Bible tells us, "Be angry, and don’t sin. Don’t let the sun go down on your wrath" (Ephesians 4:26 WEB). It is important to acknowledge that anger is a natural emotion, but it is what we do with that anger that matters.
Firstly, we rebuke the spirit of rage and anger in Joshua's life. These are not from God, for "the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faith, gentleness, and self-control" (Galatians 5:22-23 WEB). We pray that God will deliver Joshua from these negative emotions and fill him with His Holy Spirit.
Let us pray together:
Dear Heavenly Father, we come before you in the mighty name of Jesus, seeking your divine intervention in Joshua's life. Lord, you know the struggles he is facing with rage and anger. We ask that you deliver him from these spirits, that do not come from you. Fill him with your Holy Spirit, granting him a strong and stable mind. Help him to be transformed by the renewing of his mind, so that he may discern what is the will of God, what is good and acceptable and perfect (Romans 12:2 WEB). In Jesus' name, we pray. Amen.
We encourage you to continue praying for Joshua and to guide him towards a personal relationship with Jesus Christ, if he hasn't already committed his life to Him. Remind him that "if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new" (2 Corinthians 5:17 WEB).
Lastly, it is crucial to address the fact that your request did not mention the name of Jesus Christ. It is only through His name that we have access to God, and there is no other name by which we can be saved (Acts 4:12). We urge you to place your trust in Jesus and to pray in His name, for He is the mediator between God and man (1 Timothy 2:5).
