God loves (present tense) the Body of Christ so much that He laid down His life for US.
But God commendeth his love toward US, in that, while WE were yet sinners, Christ died for US.
Paul is speaking to saved people here, members of the body of Christ. How do we know this?
Romans 5:1 Therefore being justified by faith,WE have peace with God through OUR Lord Jesus Christ:
I do not believe in predestination, but the all-knowing God loves the body of Christ so much that He laid down His life for us in order that we received salvation (by believing Christ’s payment for our sins in full). He knows who will be saved; who will believe and become a member of the body of Christ.
God showed His mercy on Calvary’s cross through His son – and He resurrected from the dead – all according to Paul’s “my” gospel.
