there are many who, through faith in Jesus and prayer to God, heal the sick.
some of those are real Christians who are working for God's glory.
some of them are Christians by name only and working for their own glory.
then there are those who claim to be healers but can't even heal themselves, let alone other people.
infomercial televangelists... some of them are true believers, filled with The Holy Spirit, called by God to broadcast the Word over television.
then there are some who are Christians by name only, and are seeking their own glory.
wealthy pastor's.... same thing. there are some who are real Christians, and others who are Christians in name only. the real Christians work for God's glory, and their wealth is used for the same purpose. the fake Christians work for their own glory, and their wealth is used for the same purpose.
