3. Movement of God: In accepting the immutability of God, we are not saying that there cannot be movement, indeed, forward progress is observed within the Scriptures. Galatians 4:4 speaks of Christ’s coming “in the fullness of time.” This language suggests that prior to that point, the situation was not quite right, but at the time He came, it was. Matthew 1:1–17 argues this same point: God was guiding history through clearly discernable acts that all led up to His self-revelation in Christ (see Hebrews 1:1–2; 1 Peter 1:10–12; 2 Peter 1:19). Theologians refer to this progression of the outworking of God’s plan as Redemptive History. The Redemptive-Historical Perspective is an approach to Scripture which attempts to understand each verse, passage, and book in light of its overall contribution to the overall plan of God. It focuses upon the unity of the biblical message, not upon the minor dissimilarities that are bound to surface as His plan for the redemption of humankind and a new heaven and earth progressively unfolds.
