Thus says the Lord:
“Stand by the roads, and look,
and ask for the ancient paths,
where the good way is; and walk in it,
and find rest for your souls. —Jeremiah 6:16
As Reformed believers we understand the whole of Scripture through the lens of covenant theology. Reading through the Bible, we see God’s spotlight illuminating the Covenant of Grace, lighting the way through the history of redemption. One way to follow the path of the covenant through the scriptures is to look for the shadows cast by God’s spotlight. These symbols and figures point forward, signifying greater spiritual truths and realities. Examples of such symbols are garden and tree, water and bread, bride and groom, priest and king, wilderness and cities.
While the covenantal types and shadows may be familiar to us as Old Testament symbols, neither the symbols nor their significance diminish in importance on this side of the cross. Under the Old Covenant, believers looked forward to the coming of Christ, and in these last days, Christians await his return. But we still need encouragement to look forward. I’d like to encourage you, Dear One, based on God’s covenant promises, to find rest for your soul by looking forward in faith to the Lamb of God.
But First, Look Back
Let’s begin by looking back at the ancient path. In the book of Genesis, God made a covenant with Abraham, graciously promising to give him offspring as numerous as the stars through his son Isaac. Abraham believed this covenant promise so thoroughly that when God commanded him to sacrifice his son—his only son, whom he loved—Abraham obediently set out first thing in the morning (Gen. 22:1–3). By faith, Abraham considered that even if he sacrificed his beloved son, God was able to raise him from the dead (Heb. 11:19).
As they approached the mountain, Isaac, seeing the fire and the wood but no offering, asks, “where is the lamb?” Abraham answered that God would provide the lamb for the offering himself (Gen. 22:7–8). Sure enough, God intervened and provided a substitute.
Isaac’s question continues to echo down through the Scriptures.
Where, indeed, is the Lamb?…
