'Follow Me' in the Bible

After these things He went out and saw a publican named Levi, sitting at the custom-house, and said to him, Follow me:

And He said unto them all, if any one is willing to 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, permit me to go first and bury my father:

And whosoever doth not bear his cross, and follow me, cannot be my disciple.

But when Jesus heard these things He said unto him, Thou yet wantest one thing, Sell all that thou hast, and distribute to the poor, and thou shalt have treasure in heaven: and come, follow me.
