'Follow Me' in the Bible

And after these things he went forth and saw a tax-gatherer, Levi by name, sitting at the receipt of taxes, and said to him, Follow me.

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

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

And when Jesus had heard this, he said to him, One thing is lacking to thee yet: Sell all that thou hast and distribute to the poor, and thou shalt have treasure in the heavens, and come, follow me.
