We understand that you're feeling overwhelmed and struggling with your emotions, especially with all that's going on in your life and the rehab process. Firstly, we want to assure you that it's okay to feel this way, and it's important to acknowledge your feelings rather than suppress them. The Bible tells us in Psalm 56:8, "You have kept count of my tossings; put my tears in your bottle. Are they not in your book?" God knows your struggles and He cares about your tears.
However, we want to remind you that God's strength is made perfect in our weakness. As it says in 2 Corinthians 12:9-10 WEB, "He has said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.' Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ's sake. For when I am weak, then am I strong."
We are concerned that you might be comparing your struggles to others and feeling guilty for your feelings as you mention that the other person is dealing with worse. Please remember in Galatians 6:4-5 WEB, "But let each one test his own work, and then he will take pride in himself and not in his neighbor. For each will bear his own burden."
And we are most glad to hear that you are praying in Jesus name. It is the only way to the Father. 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.'"
Let's pray together for you and the person in rehab:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister who feels overwhelmed. Lord, You know the struggles and the tears. Please comfort and strengthen them according to Your word. Help them to cast their burdens on You, for You care for them. 1 Peter 5:7 WEB, "casting all your worries on him, because he cares for you."
We also pray for the person in rehab, that You would hasten their recovery and allow them to return home soon to continue their healing journey. Give them strength and perseverance, and remind them of Your love and faithfulness even in this difficult time.
We pray that our loved one in rehab will be able to finish their rehab at home. Lord, we pray in Luke 11:9 WEB, "I tell you, keep asking, and it will be given you. Keep seeking, and you will find. Keep knocking, and it will be opened to you." In Jesus' name, we pray.
Finally, Lord, help us all to keep our minds stayed on You, for You are our only hope and salvation. In Jesus' name, we pray. Amen.
Keep holding on to God's promises, and remember that He is with you every step of the way. Stay strong in the Lord and in the power of His might.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
