The vicarious suffering of Jesus resulted in great joy of the resurrection on Easter Sunday. Why there is great joy? Because through His suffering all humanity is saved and redeemed. In the same way all our sufferings will be turned for our favour (Rom 8:28) and great joy ( Jn. 16:20).
Lk 12:50 - Jesus considered suffering as a Baptism for the redemption of the humanity.
2 Cor 9:12 – Paul considered suffering as a means of revelation from God and manifestation of the power of the risen Christ in him.
Rom 8:28 – All sufferings will be turned for good for those who love God.
CCCc 57 – God is in no way directly or indirectly the cause of suffering.
CCCc 72 – In the original plan of God, Man should not suffer or die.
CCC 418 – Suffering, death, powerlessness, ignorance, concupiscence are the result of the original sin.
CCC 1264 – Suffering, death, ignorance, character weakness and concupiscence are the temporal punishments of the original sin which are not cancelled by baptism.
CCC 1521 – Suffering is a consequence of original sin.
GS 13 – Many of the human sufferings are not from God the good Creator. By faith in Christ Jesus and grace from God along with sincere prayers, anyone can be set free from the bondage of suffering.
CCC 2448 – Human suffering in various forms elicited the compassion of Jesus and he took it upon his body and set the humanity free from suffering. All those who believe in Him can personally attain freedom from suffering.
CCC 311 – God never gives suffering but allows it. Freedom of choice is the origin of evil. God has not created suffering or evil.
CCC 312 – God will change all our sufferings for our favour and for the glory of God through our request (prayer) and by patiently joining the Suffering Lord.
CCCc 314 - But nobody can overrule the vicarious aspect of the human suffering, though healing is a sign of the Kingdom of God. Then suffering can be a means of self purification and means of salvation for oneself and others (Col 1:24).
"People are called to joy. Nevertheless each day they experience many forms of suffering and pain." (John Paul II, Apostolic Exhortation Christifideles laici, 53: AAS 81(1989), 498. All human beings are called to joy not suffering. Therefore God has a plan for your wellness not for suffering (Jer 29:11). If there is a suffering God will turn it for your favour if you ask for it with faith or you can also retain it by your personal choice and preference. Then God gives you five special blessings such as gift of revelation, manifestation of the power of the risen lord with joy (2 Cor. 12:9), self purification, salvation for oneself and others. These blessings are also given without suffering as in the case of many saints.
"In the cross of Christ not only is the redemption accomplished through suffering, but also human suffering itself has been redeemed... In bringing about the redemption through suffering, Christ has also raised human suffering to the level of the redemption. Thus each man in his suffering can also become a sharer in the redemptive suffering of Christ." JOHN (PAUL II, Apostolic Letter Salvifici doloris, 19: AAS 76(1984), 225).
