This office the Lord Jesus did most willingly undertake, which, that he might discharge, he was made under the law, and did perfectly fulfill it; endured most grievous torments immediately in his soul, and most painful sufferings in his body; was crucified, and died; was buried, and remained under the power of death, yet saw no corruption. On the third day he arose from the dead, with the same body in which he suffered; with which also he ascended into heaven, and there sitteth at the right hand of his Father, making intercession; and shall return to judge men and angels at the end of the world.
