Exodus 19 shows Israel preparing to encounter the God who is holy. God brings His people to Sinai and invites them into covenant, but they must consecrate themselves because His presence is pure, powerful, and unapproachable on their own. However, in Jesus, the true Mediator, the holy God still calls us close, but now the barriers are removed. Through Christ’s blood we come not trembling at a distance but confidently to a holy God who makes us His priestly people.
