Here’s a good question? Why was death and burial necessary before resurrection? That’s just the way God chose to do it. But why does God wait for death and burial before He resurrects something? Frustrating
It was necessary for the Law to end its effect upon Jesus.
Or do you not know, brethren (for I speak to those who know the law), that the law has dominion over a man as long as he lives? 2For the woman who has a husband is bound by the law to her husband as long as he lives. But if the husband dies, she is released from the law of her husband. 3So then if, while her husband lives, she marries another man, she will be called an adulteress; but if her husband dies, she is free from that law, so that she is no adulteress, though she has married another man.
And for the testament, the binding will of the owner of an estate, to be transferred to the inheritors:
For where there is a testament, there must also of necessity be the death of the testator. 17For a testament is in force after men are dead, since it has no power at all while the testator lives. 18Therefore not even the first covenant was dedicated without blood. 19For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and goats, with water, scarlet wool, and hyssop, and sprinkled both the book itself and all the people, 20saying, “This is the blood of the covenant which God has commanded you.” 21Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. 22And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
So, when a man, through faith, accepts the death of Jesus as his own, he may then partake of the New Covenant secured by His death.
Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another—to Him who was raised from the dead, that we should bear fruit to God.
