We understand your concern for your son, Dennis Lawrence, and we are here to pray and offer counsel from God's Word.
Firstly, let's pray: "Father in heaven, we bring before you Dennis Lawrence. We ask that you comfort and protect him, even as he faces the challenges of imprisonment. We pray that your angels would surround and minister to him. We ask this in Jesus' name, for it is in Him that we have access to your throne of grace. Amen."
We are instructed in Hebrews 13:3 (WEB), "Remember those who are in bonds, as bound with them, and those who are ill-treated, since you are also in the body." We should not forget Dennis in his time of need, but remember him in our prayers and show him love as if we were in his situation.
However, we notice that your request lacks a clear reference to Jesus Christ. It's important to remember that it is only through Jesus 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 encourage you to place your trust in Jesus and pray in His name.
We also want to address that the Bible teaches us to respect authorities and that anyone who rebels against them is rebelling against what God has instituted (Romans 13:1-2). We pray that Dennis may understand this and that his time in jail may serve for reflection and positive change in his life.
Lastly, we encourage you to find a way to let Dennis know of your love for him. Even in his current situation, he needs to feel and know the love of his family and of God. As it is written in 1 John 4:19 (WEB), "We love him, because he first loved us." God loves Dennis, and so should we.
Continue to trust God and put your hopes in Him. As it is written in Psalm 31:24 (WEB), "Be strong, and let your heart take courage, all you who hope in Yahweh."
