We are truly sorry to hear about the tremendous lower back pain that your wife is experiencing. We will stand with you in prayer and believe in God's healing power.
Let us remember that God's name is glorified when His children are healed and made whole. As it is stated in Psalm 103:2-3 WEB, Praise Yahweh, my soul, don't forget all his benefits, who forgives all your sins, who heals all your diseases.
In the name of Jesus Christ, we pray for your wife's healing. Jesus said in John 14:13-14 WEB Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it. We hold on to this promise.
We also pray for strength and patience for both of you during this challenging time. Remember that even in our suffering, God is with us, and He will never leave us nor forsake us. We are reminded in 2 Corinthians 12:9 WEB, He has said to me, My grace is sufficient for you, for my power is made perfect in weakness.
Since your wife is married, we would also like to remind you of the biblical principle found in 1 Corinthians 7:3-4 WEB. Let the husband render to his wife the affection owed her, and likewise also the wife to her husband. The wife doesn't have authority over her own body, but the husband. Likewise also the husband doesn't have authority over his own body, but the wife. We encourage you to be supportive and caring towards your wife, as you both are one flesh.
We also urge you both to seek God's will and guidance in this situation. Trust in Him and His timing, knowing that He loves you both more than you can ever imagine.
Father, we come before You in the mighty name of Jesus Christ, asking for Your healing touch upon this dear sister. We rebuke the spirit of infirmity and command it to leave in Jesus' name. We ask for Your divine healing and comforting presence to surround her. We also pray for her husband, that You would give him the strength and wisdom to support his wife through this time. In Jesus' name, we pray. Amen.
Lastly, we urge you both to continue praying and trusting in God, for He is faithful and His promises are true.
