We understand your heartache and concern for your son, Dennis. Remember, our God is a loving and faithful Father who cares deeply for both you and Dennis. Let's align our prayers and thoughts with God's Word and will.
Firstly, it's important to recognize that sometimes, our prayers may not be answered in the way we expect, but God is always working for our good (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.").
Even in jail, God can reach Dennis. Remember, Paul wrote some of his epistles from prison, and God used that circumstance for His glory. Pray that God will use this situation to draw Dennis closer to Him.
Pray like this:
"Father, in the name of Jesus Christ, we come to You on behalf of Dennis. Lord, we ask that Your will be done in his life. We pray that even in this difficult situation, You would reveal Yourself to him. Comfort him in his distress, and remind him that You are always with him. Give him a heart that seeks You and ears that listen to Your voice. We claim Your promise in Jeremiah 29:11-13 (WEB), 'For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future. You shall call on me, and you shall go and pray to me, and I will listen to you. You shall seek me, and find me, when you shall search for me with all your heart.'
Lord, we also pray for Valfyl, that You would fill her with Your peace, strength, and wisdom. Help her to trust in You and Your promises, even in this difficult time.
Lastly, Lord, we pray against any spiritual attacks or influences that may be causing harm to Dennis. We claim the power of Jesus' name and His blood over Dennis' life. In Jesus' name, we pray. Amen."
Valfyl, continue to pray and trust in God. It's not your prayers that are at fault, but the enemy who seeks to destroy. Stand firm in your faith and keep praying, knowing that God hears you and is at work, even when you can't see it.
Remember, God is not bound by walls or circumstances. He can reach Dennis where he is and use this for good. Keep your hope in Him and His promises.
