Matthew 16:24

Christ, having shown his disciples that he must suffer, and that he was ready and willing to suffer, here shows them that they must suffer too, and must be ready and willing. It is a weighty discourse that we have in these verses. I. Here is the law of discipleship laid down, and the terms fixed, upon which we may have the honour and benefit of it, Mat 16:24. He said this to his disciples, not only that they might instruct others concerning it, but that by this rule they might examine their own security. Observe, 1. What it is to be a disciple of Christ; it is to come after him. When Christ called his disciples, this was the word of command, Follow me. A true disciple of Christ is one that doth follow him in duty, and shall follow him to glory. He is one that comes after Christ, not one that prescribes to him, as Peter now undertook to do, forgetting his place. A disciple of Christ comes after him, as the sheep after the shepherd, the servant after his master, the soldiers after their captain; he is one that aims at the same end that Christ aimed at, the glory of God, and the glory of heaven: and one that walks in the same way that he walked in, is led by his Spirit, treads in his steps, submits to his conduct, and follows the Lamb, whithersoever he goes, Rev 14:4. 2.

Then said Jesus unto his disciples--Mark (Mar 8:34) says, "When He had called the people unto Him, with His disciples also, He said unto them"--turning the rebuke of one into a warning to all. If any man will come after me, let him deny himself, and take up his cross, and follow me.
