We have so much to learn from the One who could do it all in one step, yet didn't! He forms, then fills. He saves, then sanctifies. He purposes, then perfects. Don't get in too much of a hurry. He loves the process, and so should we. 🙂
Genesis is the book of beginnings / origins. This narrative is His Story, where we find our story. It reveals the redemptive virtues of God and sets forth great Christian doctrines in seed-form.
