Before all time; prior to all worlds; when there was nothing ‘outside of’ God Himself; when the Father, Son, and Spirit found eternal, absolute, and unimaginable blessing, pleasure, and joy in Their holy triunity — it was Their agreed purpose to create a world. That world would fall. But in unison — and at infinitely great cost — this glorious triune God planned to bring you (if you are a believer) grace and salvation.
This is deeper grace from before the dawn of time. It was pictured in the rituals, the leaders, and the experiences of the Old Testament saints, all of whom longed to see what we see. All this is now ours. Our salvation depends on God’s covenant, rooted in eternity, foreshadowed in the Mosaic liturgy, fulfilled in Christ, enduring forever. No wonder Hebrews calls it ‘so great a salvation’ (Heb. 2:3).
