At sunrise God calls his people to come into His Presence to renew their covenant relationship with the God of Love and Salvation. Sunrise is a reminder of the Lord’s coming into our lives to make a promise, whether at Sinai (for OT believers) or Golgotha and Garden (for NT believers).
He set up an elaborate sacrificial system, and now he says he doesn’t need your sacrifices. You need it, and God wants you, in a loving relationship with him. Since Jesus’ once for all sacrifice for your life, your sacrifices are no longer needed. Ah, but you do need to make daily sacrifices, because you forget. How do we sacrifice today? Remember your Baptism by repentance and thanksgiving and renewing a relationship of pure Grace. Sacrifice is dying to self, surrendering self-will, giving up control, being willing to let go, laying down life for the sake of others; in other words, repent and believe the Gospel. Then Thanksgiving erupts from a life full of joy, and “call on Him in the day of trouble.”
Coming into the Presence also involves a warning and a judgment against hypocrisy and ritual and disregarding the relational consequences of the Ten Commandments; these are defeated enemies. We Worship in Spirit and Truth.
