Predestination means that from all eternity God has determined upon man’s acquittal at His own cost- Karl Barth.

“The exchange which took place on Golgotha, when God chose as His throne the malefactor’s cross, when the Son of God bore what the son of man ought to have borne, took place once and for all in fulfilment of God’s eternal will, and it can never be reversed. There is no condemnation—literally none—for those that are in Christ Jesus. For this reason faith in the divine predestination as such and per se means faith in the non-rejection of man, or disbelief in his rejection. Man is not rejected. In God’s eternal purpose it is God Himself who is rejected in His Son. The self-giving of God consists, the giving and sending of His Son is fulfilled, in the fact that He is rejected in order that we might not be rejected. Predestination means that from all eternity God has determined upon man’s acquittal at His own cost. It means that God has ordained that in the place of the one acquitted He Himself should be perishing and abandoned and rejected—the Lamb slain from the foundation of the world. There is, then, no background, no decretum absolutum (absolute decree), no mystery of the divine good-pleasure, in which predestination might just as well be man’s rejection. On the contrary, when we look into the innermost recesses of the divine good-pleasure, predestination is the non-rejection of man. It is so because it is the rejection of the Son of God. It is so because it is indeed a foreordination of the necessary revelation of divine wrath—but a revelation whose reality was God’s own suffering in Jesus Christ. Only if we are unbelieving or disobedient or unthankful in face of what is ordained for us, only if we misunderstand completely the divine predestination, can we think of this revelation as something which has to do with our own suffering. If in face of the divine predestination we are believing and obedient and thankful, if we have a right understanding of its mystery, we shall never find there the decreed rejection either of ourselves or of any other men. This is not because we did not deserve rejection, but because God did not will it, because God willed the rejection of His Son in our stead”. [1]
