The term Christian means "like Christ." There are many false and fake Christians, just as there have always been many false and fake Christs. This is no mean-spirited attack. This is simply the Truth. An apple tree is a tree which by design, nature and function produces apples. That is the simple truth. Now an actual apple tree could be dormant or unproductive or dead, but those are themselves other issues. God commands His people to be instant in season and out of season. Christ is Christ in action, in word and in demonstration every day. To be Christian is by simple definition to be like Christ. Anyone who does not live and do, preach and teach what Christ did and what Christ does is by definition not actually Christian. To be Christian indeed, in action is both to live and to preach the Good News of the Gospel.
