This document discusses how Jesus fulfilled the spring feasts of Passover, Unleavened Bread, and Firstfruits in the Bible, and how he represents the mercy seat in the Holy of Holies. It notes how the high priest would sprinkle blood on the mercy seat once a year for atonement, and how Jesus' blood was sprinkled once to provide perpetual atonement and grace. The document contrasts grace through faith in Jesus with the law that shows mankind's inability to attain righteousness through works. It presents Jesus as the king who keeps the mercy seat and law covered by his blood so that mercy and grace can always be found.
