I am ill. Will God heal me?
God heals, and God does not always heal in this life, and both of those are in the Bible without embarrassment. Ask boldly — Scripture tells you to call for the elders and pray. Use medicine fully; Luke was a doctor, Paul prescribed for Timothy's stomach, and nothing in Scripture treats treatment as unbelief. And guard your heart against anyone who tells you that continued illness proves you lacked faith or gave too little money. Paul asked three times and was not healed, and he was not deficient.
Go and see for yourself
Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
