Christ is the firstfruit of the risen (1 Corinthians 15:20).

In Leviticus 23:10 God tells Israel that they are to bring the firstfruits of their first Harvest of the promised land to Him. No grain was sown in the desert and the manna stopped with the firstfruits.

Christ rose from the dead on the day of the Festival of Firstfruits. By His death and resurrection, by His substitutionary sacrifice, He took away our reproach.
