Christ's suffering is finished. But in another sense, His suffering continues through the suffering of the church as it preaches the message of the crucified Savior. He suffered as a man, he suffered for man and he suffers from man. The first two are history, the third is ongoing. The first two are finished and complete. The last one is unfinished and incomplete. He who knew no sin, absorbed the wrath of God concerning our sin. And in a wonderful exchange, God put our sin on Christ, and if we'll put our fear in Christ, His righteousness becomes ours. Jesus’ suffering for man is complete. You don't need to do anything for God to accept you. You just need to throw your arms around the one God loves most of all, His Son, and be amazed at God's love for you in His Son. Jesus Christ offered Himself once forever, and obtained for us eternal salvation. Jesus' death doesn't need to be repeated in a mass. Jesus' death doesn't need to be added to in tenants, or good works, or religious activity. He offered a full, and final, and forever sacrifice for sin.
