And looking upon Jesus as he walked, he said, Behold the Lamb of God!
All Commentaries on John 1:36 Go To John 1
Cornelius a Lapide
AD 1637
And seeing Jesus as he walked, &c. As though he said, "Behold Christ like a spotless Lamb, destined for a victim, that He may be offered to God upon the cross, for the sins of the whole world." When John spoke thus it was as though he said to his disciples, "Why do you follow me? follow Him who is the Lamb of God, the ransom of the world."
Here observe the prudence and modesty of John. He does not compel or urge his disciples to follow Christ, but only points Him out to them, that they might the more ardently pursue after so great a good when it was discovered by themselves. Like a man who, when a jewel is being sold for a small price, points out to merchants how great is its worth, and causes them of their own accord to long to purchase it.
