Verily, verily, I say unto you, He that believes on me has everlasting life.
All Commentaries on John 6:47 Go To John 6
Cyril of Alexandria
AD 444
Faith therefore is the door and way unto life, and return from corruption unto incorruption. But herein no less is the economy a marvel to the learners: for when He perceived that they understood nothing at all, and saw that they did not suppose they ought to give any credence even to the words of the Prophets, He cuts off, as far as possible, their weakness unto faith by human arguments, by an oath to its truth. For setting before them which believe much to be envied prizes, with their longing desire for these as with traces. He all but constrains them against their will, and persuades them to come to what is proclaimed to them. For what would be more precious than eternal life, to them to whom death and the sufferings from decay are bitter? And this too will beseem a wise teacher, to re-instruct unto the better, by every way (I say) that invites unto life, them who have chosen to think foolishly. But He, being Eternal Life, promises to give Himself to them that believe: that is, that Christ may dwell in our hearts by faith.
