SEV Biblia, Chapter 21:21
Así que cuando Pedro vio a ste, dice a Jess: Seor, ¿y ste, qu?
John Gill's Bible Commentary
Ver. 21. Peter seeing him, saith to Jesus , etc.] Peter took a great deal of notice of John, and very likely understood, that he meant by his rising up and following Christ, to signify his readiness for service and suffering in the cause of Christ: and therefore says, Lord, and what shall this man do ? The phrase in the original is very short and concise, Lord, and this what? The Arabic version renders it, and this, of what mind is he? it looks as if he was of the same mind with me to follow thee; but it is better rendered by us, what shall this man do? in what work and service shall he be employed, who seems as willing as I am to serve thee? or it may be rendered thus, and what shall this man suffer? shall he suffer at all? and if he shall, what kind of death shall he undergo? what will become of him? what will be his end? how will it fare with him? this he said, partly out of curiosity, and partly out of concern for him, they two being associates and intimates, who had a strong affection for each other.
Matthew Henry Commentary
Verses 20-24 - Sufferings, pains, and death, will appear formidable even to the experienced Christian; but in the hope to glorify God, to leave sinful world, and to be present with his Lord, he becomes ready to obe the Redeemer's call, and to follow Him through death to glory. It is the will of Christ that his disciples should mind their own duty, an not be curious about future events, either as to themselves or others Many things we are apt to be anxious about, which are nothing to us Other people's affairs are nothing to us, to intermeddle in; we mus quietly work, and mind our own business. Many curious questions are pu about the counsels of God, and the state of the unseen world, as to which we may say, What is this to us? And if we attend to the duty of following Christ, we shall find neither heart nor time to meddle with that which does not belong to us. How little are any unwritte traditions to be relied upon! Let the Scripture be its own interpreter and explain itself; as it is, in a great measure, its own evidence, an proves itself, for it is light. See the easy setting right suc mistakes by the word of Christ. Scripture language is the safes channel for Scripture truth; the words which the Holy Ghost teaches 1Co 2:13. Those who cannot agree in the same terms of art, and the application of them, may yet agree in the same Scripture terms, and to love one another.
