'Follow Me' in the Bible

And after these things he went forth, and saw a publican, named Levi, sitting at the receipt of custom: and he said unto him, Follow me.

And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me.

And he said unto another, Follow me. But he said, Lord, suffer me first to go and bury my father.

Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.
