We are with you in spirit and lifting up your loved one in prayer. Firstly, it is important to remember that God is with us even in the most difficult of circumstances. As it says in Matthew 28:20 WEB, "Behold, I am with you always, even to the end of the age. Amen."
As you have asked for protection and well-being for your loved one, we pray that God will shield and guide them during this time. We pray Psalm 91 over them, "He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, 'He is my refuge and my fortress; my God, in whom I trust.' For he will deliver you from the snare of the fowler, and from the deadly pestilence. He will cover you with his feathers. Under his wings you will take refuge. His faithfulness is your shield and rampart" Psalm 91:1-4 WEB.
We also pray that God will use this time for His purposes, working in your loved one's heart and mind. As it says in Romans 8:28 WEB, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
However, we must also 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's throne of grace. As it says 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.'" Therefore, we encourage you to come before God in Jesus' name. Also, remember that we are all sinners and must believe in Jesus Christ to be saved. That is the basic salvation message.
Lastly, we want to remind you of the importance of praying for God's will to be done, not just our own desires. We must trust that God knows what is best for us and our loved ones, even when it is difficult to understand. As it says in Luke 22:42 WEB, "saying, 'Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.'"
Heavenly Father, in the name of Jesus Christ, we lift up this loved one who is incarcerated. We pray for their protection, their well-being, and their spiritual growth. We ask that Your will be done in their life, and that You use this time for Your purposes. We also pray for the one who submitted this request, that You would give them peace and comfort during this time. Help them to trust in You and to come before You in Jesus' name. It is only through Him that we can come to You and be saved. We ask this all in Jesus' name, Amen.
