“A third reason why Jesus is the Good Shepherd is that He draws and gathers His lost sheep to Himself. He says, ‘I have other sheep which are not of this fold; I must bring them also (v.16). This allegory began with Jesus calling His sheep out of the spiritual deadness of apostate Israel. When He says that He as ‘other sheep’ that are not of this fold, He refers to Gentile sheep that are outside the fold of Israel. Jesus must also draw them to Himself. They will come from ‘every bribe and tongue and people and nation’ and comprise a number that is ‘myriads of myriads, and thousands of thousands.’ (Rev.5:9,11)
