READ : John 4:46-54
“When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.” – John 11:4
The above verse shows that God heals for His glory to be revealed. When we have miracles in the church, it is because God wants us to get glimpses of His glory. He wants us to see His power. He wants to show us that He is the Almighty God and that there is no problem too big for Him to solve.
Sometimes the problems we have are going to lead to the greatest blessings in our lives. God is going to use that thing to bring a great miracle into your life. I see that miracle coming into your life!
God heals to confirm the Word of God that has been preached (Mark 16:20). Miracles have a primary function of confirming the preaching of the Word of God. This is different from eradicating all the diseases in the community. Confirming and affirming a sermon preached by a pastor is quite different from eradicating polio, measles or small pox from a community. Believe me that I am in the Father, and the Father in me: or else believe me for the very works’ sake. John 14:11
Some people just want to see a miracle so that they can believe. Such people just need a miracle. When they see the works, they are utterly and completely convinced about the truth of the Word. God does miracles to help some people believe.
