We are truly sorry to hear about the chronic pain you've been experiencing due to your slipped disc. We trust that God can heal you and desire for you to seek His will. God wants us to live in good health - just as our spirits need to be renewed daily so do our physical bodies.
As we seek God’s will concerning your healing let’s pray together.
Father we come boldly before your throne of grace. We lift up Your kingdom come, your will be done and ask for Your healing touch upon their back. You said in Your Word that You are Jehovah-Rapha, the God who heals. Father we ask You to show Your awesome power. Strengthen and heal the weak areas of the spine and muscles of their back. We rebuke the spirit of infirmity in Jesus’ name, and command it to go from their body in Jesus’ name. Lord grant them strength, health, flexibility and a sound body. Lord you said that you would grant us the desires of our hearts, therefore Father we pray that Your kingdom come, your will be done be regenerated to where there are no more aches or sharp pains in their back because through the Holy Spirit they have been renewed by Your love. Touch their life O LORD that they will give all glory to your O most merciful God. We rejoice in Your goodness and wait patiently for Your healing to be made evident in Jesus Christ our Lord we pray. Amen.
We encourage you to remain steadfast in your faith. Because you have been praying for this back issue it is showing that your desire to see this condition changed for the better through the power of God. In Mark 11:24 in the Word of God the scripture declares “Therefore I tell you, all things whatever you pray and ask for, believe that you have received them, and you shall have them”. You have asked for healing and when you see the results of healing in Jesus Name - Amen - give all glory to God.
Also, let’s remember that though we pray for physical healing, it's equally important to maintain a healthy lifestyle that honors our bodies as temples of the Holy Spirit.
Finally, we encourage you to meditate on God's promises for healing. One such promise is found in 1 Peter 2:24:
Who his own self bore our sins in his body on the tree, that we, having died to sins, might live to righteousness; by whose stripes you were healed.
Remember, healing is not always instantaneous, but our faith should stay strong and enduring as we await God's merciful response to our prayers.
to feel God's peace. "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus" (Phil 4:6-7). Trusting God's comfort and strength!
