Most Christians know that salvation is God's will for everyone, but they don't know that healing is God's will for everyone. We understand the will of God for salvation because we have Scriptures which reveal that. We've been taught those Scriptures. We haven't been taught the Scriptures which reveal God's will concerning healing; therefore, we've ignorantly concluded that we don't know if it's God's will to heal us today. Our ignorance is from a lack of studying the Bible for ourselves, and choosing to listen to ministers who haven't spent any time studying the healing Scriptures, and therefore are not qualified to teach on the subject. Don't conclude that healing is not for everyone, since everyone won't be healed. Your conclusion should be based on God's Word, not people's experiences. We would never conclude that salvation is not for everyone, even though everyone won't go to Heaven.
