We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
(Romans 6:4 NIV)
As a born again believer, it's important you know and understand that when Jesus died you were together with Him, when He was buried you were together with Him, and when He rose from the dead with the resurrection life that's sickness, disease and death proof, you were also together with Him. Thus, as a possessor of eternal life, it means you have the sickness proof life. You're impregnable to sickness and disease by reason of the God Life in you.
Eternal life doesn't need healing. Rather, God expects you to heal others for you carry His divine life. Mark 16:15-18 (NKJV) explains, "And He said to them, “Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned. And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover."” The Word of God is for doing. If God said you're to lay your hands on the sick and they'll recover, that's what's you're supposed to do. He's given you His life– the ability and anointing to heal the sick.
Eternal life is also death proof, it doesn't die. John 11:25-26 says, "Jesus said to her, “I am the resurrection and the life. He who believes in Me, though he may die, he shall live. And whoever lives and believes in Me shall never die. Do you believe this?” John 3:36 let's us know that those who believe in Jesus have everlasting life– the life of God that doesn't die! Hallelujah.
When you have eternal life, life and immortality are at work in you always, and this ought to be your daily confession: "Life and Immortality are at work in me. I shall live and not die for I have the God Life in me". You see, with this life, nothing in you dies; nothing in your body dies, your businesses, relationships and your ministry don't die. Your responsibility is to cultivate a consciousness of these truths and realities by contlsantly meditating upon and making confessions of them.
By reason of the God Life in me, I'm impregnable to sickness and disease. Death has been defeated in my life for I have the everlasting life of the Father. Nothing dies in my hands, rather healings, miracles and life flow from the rivers of living waters within me.
