“Christ suffered in his body” some translate have “died”. Jesus suffered physically a great deal from the time He was arrested until His death on the cross. The greatest suffering was as Jesus was dying on the cross when the sins of the whole world came upon Him. The full penalty for our sins has been paid for by Jesus. To receive this blessing is to obey Jesus’ command in becoming a Christian as the Scripture teaches. Jesus suffering only took place while He was in the flesh here on earth.
He “is done with sin” is telling us there is no more sacrifice for sins. Christ died once for all. His sacrifice does not need to be repeated for Jesus was the perfect sacrifice. The penalty for sinning has been paid for with Jesus Christ shed blood. You can be saved from the “guilt” of sin when you are immersed into Christ; then you are saved from the “power” of sin daily and you will be saved from the consequence of sin when you are received into heaven. The “he” may refer to either Christ or the Christian. Christ has done His part. As Christians we will sin, but as we determine to do better, our faith will be strengthened and we will have the power to resist temptations. Not only that, but Jesus will bless us for suffering for Him. For all this to happen, each individual must have the right relationship with Jesus by believing, repenting, confessing, being immersed into Christ and faithfully serving Him unto death.
