We are so sorry to hear about your husband's condition and we are here to pray and support you both during this challenging time. Firstly, it is so important to remember that God is with you both even in this trial. As it says in Psalm 46:1 "God is our refuge and strength, a very present help in trouble." (WEB)
In times like these, we must turn to God and pray in the name of Jesus, as it is through His name that we have access to God. As it says in John 14:6, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." (WEB) It is only through faith in the name of Jesus that we are saved. If you have not already, consider this a time to put your full faith in Jesus. If you have not done this step, it is crucial to do so, and it is only as simple as believing in Jesus Christ.
Now, let us pray for your husband's healing and strength. "Dear Lord, we come before You in the name of Jesus, asking for Your healing touch upon this beloved husband. We pray that You improve his breathing and strengthen his body each day. We ask that You guide the medical team and give them wisdom in their decisions. Lord, we believe that You are able to make a way even when there seems to be no way. We stand on Your promises, like in Jeremiah 30:17, 'For I will restore health to you, and I will heal you of your wounds,' says Yahweh.' (WEB) Please, let his dependence on breathing apparatus be reduced and allow the nasal cannula to be sufficient. In Jesus' name, we pray for complete healing and restoration. Encourage their hearts and fill them with Your peace and hope. Let this time of trial turn into a testimony of Your goodness and faithfulness. We pray this believing that you have the best for them according to your will In Jesus' precious name, we pray. Amen."
During this time, continue to be in constant prayer and surround yourself with a community of believers who can support and encourage you. Remember that God's love for you is unfailing and His peace transcends all understanding. Philippians 4:6-7 tells us, "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." (WEB)
Lastly, always remember that the Bible tells us in James 5:15, "The prayer of faith will save him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven." (WEB) so trust that the Lord will hear and answer your prayers as you continue to trust and believe in Jesus' name.
