Colossians 1:24: Now I can find joy amid my sufferings for you, and I fill up in my own person whatever is lacking in Christ's afflictions on behalf of His Body, the Church.
There are no afflictions lacking in Christ's sufferings. His sacrifice is complete, he is in glory, seated at the right hand of the father, his work of atoning redemption fulfilled.
Paul is referencing his own sufferings, and paralleling them to the sufferings of Christians in the church. The KJV translation makes more sense: "...and fill up that which is behind of the afflictions of Christ in my flesh"
Rather:
"The death he died, he died to sin once for all..."
Romans 6:10
"He sacrificed for their sins once for all when
he offered himself." Hebrews 7:27
"He entered the Most Holy Place once for all by his
own blood, having obtained eternal redemption."
Hebrews 9:12
"But now he has appeared once for all at the end
of the ages to do away with sin by the sacrifice
of himself." Hebrews 9:26
"so Christ was sacrificed once to take away the
sins of many people...." Hebrews 9:28
"we have been made holy through the sacrifice of the
body of Jesus Christ once for all." Hebrews 10:10
Colossians 1:24: Now I can find joy amid my sufferings for you, and I fill up in my own person whatever is lacking in Christ's afflictions on behalf of His Body, the Church
Col 1:24 Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church:
Nice try but no cigar...You leave out words, you can make it mean anything you want, can't you???
What you are saying then is Christ's sacrifice on the cross 'alone', isn't sufficient for YOU...
