'Follow Me' in the Bible

And after these things he went forth, and saw a tax collector, named Levi, sitting at the tax office: 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, allow me first to go and bury my father.

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