They went out from us, but they didn't belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us.

 The great aim of all religion is fellowship with God, to know him as friend and to enter with joy, and not fear, into his presence. It therefore follows that the supreme problem of religion is sin, for it is sin that interrupts fellowship with God. It is to meet that problem that all sacrifice arises. By sacrifice fellowship with God is restored. So the Jews offered, night and morning, the sin-offering in the Temple. That was the offering, not for any particular sin but for man as a sinner; and so long as the Temple lasted it was made to God in the morning and in the evening. The Jews also offered their trespass-offerings to God; these were the offerings for particular sins. The Jews had their Day, of Atonement, whose ritual was designed to atone for all sins, known and unknown. It is with that background that we must come at this picture of propitiation.
