Are You Really A Christian?

How do people know if they are really a Christian? Is it through the way they look or the good works that they do or is there another way? Appearing to be a Christian 'outwardly' doesn't necessarily mean that a person is a Christian 'inwardly'. Author Harold Cluck shows through Scripture the steps necessary to know Are You Really a Christian? Jesus said in Matthew 24:42, 'Therefore keep watch, because you do not know on what day your Lord will come.'
