[K]nowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, 19 but with the precious blood of Christ, as of a lamb without blemish and without spot. 20 He indeed was foreordained before the foundation of the world, but was manifest in these last times for you 21 who through Him believe in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God. 1 Peter 1:18-21 NKJV
According to Christian tradition, Easter Sunday is observed the first Sunday, after the first full moon, after the vernal equinox (March 21st). Easter is a celebration of the resurrection of Jesus Christ from the dead. He was crucified on Israel’s day of Passover and rose from the dead on the third day, according to the Scriptures. Easter is about a redemption story, i.e., a repurchase of fallen mankind; the recovery of ownership of the human race by Jesus Christ paying a specific sum, i.e., His blood.
Jesus was sent to earth on a specific mission: to act out in time and space what God had done in eternity (Rev. 13:8; Eph. 1:4; John 1:29). His mission was to (1) seek and save (Luke 19:10); (2) destroy the works of the Devil (1 Jn. 3:8); and, (3) to heal, deliver, and restore man (Act 10:38). .
Jesus had to died for mankind because the Law—ordinances of sin and death—was insufficient to satisfy the judgment of God against sin (Heb. 10: 1-9; Rom. 5:8). The Law could not perfect fallen man in the eyes of God, but Jesus could. He finished the work of atonement (John 19:30), nailing the Law to the cross (Col. 2:14), perfecting forever them who are sanctified (Heb. 10:14), and finishing our faith (Heb. 12:2). Jesus’ death, burial, and resurrection was Jesus’ mission accomplished!
