“And they said unto him, We can. And Jesus said unto them, Ye shall indeed drink of the cup that I drink of; and with the baptism that I am baptized withal shall ye be baptized:”
King James Version (KJV)
10:38 Ye know not what ye ask - Ye know not that ye ask for sufferings, which must needs pave the way to glory. The cup - Of inward; the baptism - Of outward sufferings. Our Lord was filled with sufferings within, and covered with them without.
10:40 Save to them for whom it is prepared - Them who by patient continuance in well doing, seek for glory, and honour, and immortality. For these only eternal life is prepared. To these, only he will give it in that day; and to every man his own reward, according to his own labour.
