'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 to him, Follow me.

And he said to all, If any man wants to come behind me, let him deny himself, and take up his cross, and follow me.

And he said to another, Follow me. But he said, Lord, allow me first, after departing, to bury my father.

And when he heard these things, Jesus said to him, Yet one thing is lacking from thee. Sell all things, as many as thou have, and distribute to the poor, and thou will have treasure in heaven. And come, follow me.
