Christ Suffered

Jesus suffered "once" for sins. The primary reason Christ died is to bring us to God. His death fully satisfied God's wrath, nothing else is needed or necessary for our salvation. He died once for all.
He suffered for sin-past, present and future. We must remember that God' s wrath is an infinite wrath.
Again, Jesus suffered God's wrath to bring us to God=-His purpose being to bring us to God.
