Had God rejected Jesus on the cross, we would still be in our sins!

Throughout the Old Testament the offerings which foreshadowed Jesus were ACCEPTED to make atonement. Those offerings which were rejected did not make atonement.

And he shall put his hand upon the head of the burnt offering; and it shall be ACCEPTED for him to make atonement for him (Leviticus 1:4).

And if any of the flesh of the sacrifice of his peace offerings be eaten at all on the third day, IT SHALL NOT BE ACCEPTED, neither shall it be imputed unto him that offereth it: it shall be an abomination, and the soul that eateth of it shall bear his iniquity (Leviticus 7:18).

Rejected sacrifices and offerings DID NOT make atonement. Those which were accepted as a sweet savor did!

And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweet smelling savour (Ephesians 5:2).
