1) Why is it necessary that Christ should be both God and man in the one and the same person?
4. That the work of redemption performed in the flesh of the Son might become a sufficient price for sin, whereby God, that infinite good, was offended. For although certain actions do properly proceed from the divine nature, and some are done by the human, yet all of them do equally receive their price and worthiness from the divine nature. So the flesh of Christ has power to quicken, because it is the flesh of that person who is God: the obedience of the man Christ does justify, because it is the obedience of that person who is God: the blood of Christ redeems the church, because it is the blood of God, Act. 20:28.

2) What was the end of Christ’s death and passion?
The chief end is the glorification of God for his justice and mercy. But the next end is the redemption and eternal salvation of mankind, Joh. 3:14, “As Moses lifted up the serpent in the wilderness, so must the Son of man be lift upon the cross, that whosoever believes in him should not perish, but have everlasting life.” And Rom. 4:25. “He died for our sins,” namely to make satisfaction for them.
Unto whom is the death and passion of Christ profitable?
Although he might have been a sufficient price for the sins for all men, yet actually and effectually he died for his elect only, who receive him and believe him, Matt. 1:21. “He will deliver his people from their sins.” Joh. 10:15. “I lay down my life for my sheep.” and Chap. 17:19 “I sanctify myself,” for otherwise it would follow that Christ died profit, and to no purpose in regard of many, and that the efficacy of Christ’s death could be made void by men.
