John 1:37 - Albert Barnes' Notes on the Bible

They followed Jesus - They had been the disciples of John. his office was to point out the Messiah. When that was done, they left at once their master and teacher, John. and followed the long-expected Messiah. This shows that John was sincere; that he was not desirous of forming a party or of building up a sect; that he was willing that all those whom he had attracted to himself by his ministry should become followers of Christ. The object of ministers should not be to build up their own interests or to extend their own fame. It is to point men to the Saviour. Ministers, however popular or successful, should be willing that their disciples should look to Christ rather than to them; nay, should forget them and look away from them, to tread in the footsteps of the Son of God; and the conduct of these disciples shows us that we should forsake all and follow Jesus when he is pointed out to us as the Messiah. We should not delay nor debate the matter, but leave at once all our old teachers, guides and companions, and follow the Lamb of God. And we should do that, too, though “to the world” the Lord Jesus may appear, as he did to the multitude of the Jews, as poor, unknown, and despised. Reader, have you left all and followed him? Have you forsaken the guides of false philosophy and deceit, of sin and infidelity, and committed yourself to the Lord Jesus Christ.
