We are deeply moved by your request and will stand with you in prayer for your son. Let's bring his situation before the Lord, trusting in His mercy and power to heal and restore.
Firstly, we want to remind you of God's great love for us, as written in John 3:16 (WEB), "For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life." This love extends to your son, and we can approach God's throne with confidence, knowing He cares for him.
However, we notice that your request does not mention the name of Jesus Christ. It is by His name that we have access to God, as it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" We will pray in the name of Jesus, as it is the name above all names, and the only name by which we can be saved (Acts 4:12).
Let's pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our beloved brother who is struggling with mental illness and homelessness. Lord, You know his situation and the desires of his heart. We ask that You have mercy on him and provide him with food, shelter, and healing both physically and mentally.
Father, we also pray for his salvation, that he may come to know Jesus Christ as his personal Lord and Savior. We believe that You have a plan and a purpose for his life, and we ask that You reveal this to him, drawing him closer to You.
We stand against any spiritual forces that may be causing or exacerbating his condition, and we pray for his complete deliverance and restoration in the name of Jesus Christ (Matthew 12:28).
We ask all these things in accordance with Your will, trusting in Your goodness and love. In Jesus' name, we pray. Amen."
We encourage you to continue praying for your son, trusting in the power of God to turn his situation around. Remember the promises of God, such as Jeremiah 32:27 (WEB), "Behold, I am Yahweh, the God of all flesh. Is there anything too hard for me?" Keep believing and keep praying, knowing that God is able and willing to work in your son's life.
