Who is Jesus? It is good that we know who the Jesus of the Bible is, that we fully know who Jesus is. For many Jesus was only a common man, for others a prophet, for others a myth, and for many others like us Jesus is God, and that of which He is God, also the Bible attributes some names to Him that it is good that we know.
Jesus is the good shepherd
Jesus is the good shepherd, the one who gives His life for the sheep, and demonstrated it in the best way, giving His life for each one of us to give us salvation.
11 I am the good shepherd: the good shepherd giveth his life for the sheep.
12 But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.
13 The hireling fleeth, because he is an hireling, and careth not for the sheep.
14 I am the good shepherd, and know my sheep, and am known of mine.
