God and Christ knew from the beginning, of the apostasy of Satan and of the fall of Adam through the deceptive power of the apostate. The plan of salvation was designed to redeem the fallen race, to give them another trial. Christ was appointed to the office of Mediator from the creation of God, set up from everlasting to be our substitute and surety. Before the world was made, it was arranged that the divinity of Christ should be enshrouded in humanity. "A body," said Christ, "hast thou prepared me." But he did not come in human form until the fulness of time had expired. Then he came to our world, a babe in Bethlehem.

Helt fra begyndelsen viste Gud og Kristus at Satan kom til at gøre oprør, og at Adam ville komme til at falde som en følge af oprørerens evne til at vildlede. Frelsesplanen blev lagt for at kunne genløse den faldne menneskehed og give dem en ny anledning. Gud gav Kristus opgaven som mellemmand. Fra evighed af var han bestemt til at være vor stedfortræder. Før verden var skabt, blev det aftalt at Kristi guddom skulle iklædes menneskelighed. Jesus sagde: Derfor siger han, da han træder ind i verden: Slagtoffer og afgrødeoffer vil du ikke have, men et legeme har du beredt mig. (Hebr 10,5). Men som menneske kom han først i tidens fylde. Da kom han til vor verden som barnet i Betlehem.
