In his high priestly prayer of intercession on behalf of his disciples, Jesus asks his Father for those things which would be essential for them.

Oneness is an intriguing inclusion. Presumably Jesus, with his insight into human nature, would have known just how challenging being one would prove to be for his followers. Setting aside the splintering of the church into uncountable denominations, it is difficult enough for a single congregation to be one.

Yet the disciples being one is a key and powerful testimony to the truth of who Jesus is. It is also a persuasive pointer to the salvation of the world.
