The Old Testament required that a perfect without blemish or spot be sacrificed for sin. Christ's sacrifice was a of the Old Testament requirement. The options for the first one are: dove, salvation, or lamb. The options for the second one are: resurrection, obligation, or fulfillment. You can only choose one answer!

lamb, fulfillment

Explanation:

The sacrificing of a lamb was carried out multiple times throughout the old testament as a type of absolving of sins. This is seen most clearly in the plague that the Israelites evaded by placing an x made of blood above their doors.

For the second, fulfillment is the only one that makes sense in the sentence because in order for it to be a sacrifice it had to be a decision and this is shown in the garden scene, because even though it wasn't what he wanted he still followed through with God's will.

The first blank is lamb and the second blank is fulfillment
