Everything belongs to God, and all things were created by his power. So God did the right thing when he made Jesus perfect by suffering, as Jesus led many of God's children to be saved and to share in his glory.
Christ carried the burden of our sins. He was nailed to the cross, so that we would stop sinning and start living right. By his cuts and bruises you are healed.
Christ died once for our sins. An innocent person died for those who are guilty. Christ did this to bring you to God, when his body was put to death and his spirit was made alive.
