Three reasons to keep reading the Old Testament


The Old Testament causes much consternation among North American evangelicals. Although historically, Christians have embraced the Old Testament as being absolutely essential to the Christian life—I believe the first person to do this was Jesus—somewhere along the way, we got scared of it.

We started reading into the New Testament a kind of sentimental love that isn’t there. We started seeing the actions of God in the Old Testament as harsh and mean. And as our sentimentalism took root, we found ourselves asking, “can’t we just skip this?”

Here are three reasons to keep the Old Testament front and center:

1. To understand God’s actions in the world. To not put too fine a point on it, when you lose the Old Testament, you lose the gospel. Period.

The Old Testament is the historical backdrop for everything we see in the New. The gospel takes place within the framework of the covenants established with Adam, Noah, Abraham, Moses and David, and fulfills them. If you do not have the Old Testament, you cannot understand why Christ came to die. We lose the foundation for his death and resurrection.

But when you maintain a solid grasp on the Old Testament, you not only keep the gospel’s foundation, you get the fuller picture of God’s actions in the world. The entire Bible tells the story of God’s war against sin—from the first promise of the coming of one who would crush the head of the serpent until the consummation of the new creation, this is what God is doing.

When you lose the Old Testament, you lose the reason for God’s actions in the world. You lose the gospel. So read the Old Testament.

2. To understand the character of God. When we skip the Old Testament, we lose a clear picture of who God is. In his Christianity Today article addressing this very subject, Mark Gignilliat puts it well:

We do no favors for God or ourselves when we lessen his severity, even in our attempts to make him acceptable to non-believers. While many of our worship songs today speak of touching and seeing God, most biblical characters did not line up for such an opportunity. Isaiah knew his life was over after seeing Yahweh. Jacob never walked the same way again. Job asked for a day in court with God and then regretted it.

We cannot understand God’s character without reading the Old Testament. He reveals himself in all his perfection there. His holiness is on display—and his love is magnified more deeply because we understand just how great our offenses are. So read the Old Testament.

3. To avoid becoming a heretic. This might seem ironic considering just yesterday I wrote about our need to not cheapen words like this one. But if you skip over the Old Testament consistently, if you create a false dichotomy in the Bible, you’re going to fall into heresy. Here are two common heresies that stem from rejecting the Old Testament:

Marcionism. A heresy that emerged around the year 144, this is a dualistic view that rejects the Old Testament and the God of Israel as being a tyrannical monster where the God of the New is a God of love and peace. This is the god we see in Rob Bell’s Love Wins, Brian McLaren’s New Kind of Christianity, and so many others (whether it’s outright stated or not is another question). But more practically, it’s the god of anyone who says, “I could never believe in a God who…”

Antinomianism. This is the more subtle heresy because it’s harder to spot. In its crassest forms, antinomianism proposes that we don’t need the Old Testament—and more specifically, the Mosaic Law—at all anymore. It has no good purpose or benefit for the Christian. It suggests Jesus obliterated, rather than fulfilled the Law. Yet, this is what Paul warned of in Romans 6:1, “What shall we say then? Are we to continue in sin that grace may abound?” And his answer, “By no means! How can we who died to sin still live in it?” (Rom 6:2).

But we still need the Law—not as a means of earning salvation (for it was never that to begin with), but to see the perfection of God, to see the requirements of holiness, to see how far we fall short and our desperate need for rescue.

If we lose the Old Testament, we lose all of this. We lose all hope, all joy, and all purpose in the Christian faith. So, Christian, read the Old Testament.

  1. I think another reason for reading both the Old Testament and the New Testament is that it is all God’s Word and I can’t remember where it says to embrace the full counsel of God .The preachers in our church have been teaching from the pulpit – mainly one book of the Bible at a time (not skipping anything) I really appreciate this.

  4. Deut. 28. And all that came forth from that chapter including what is yet to be fulfilled.

    We learn of the Rock of blessing and the Rock of judgment in the OT. Oh, and those prophets … did they understand when they proclaimed “so says the LORD” explaining what will happen 1000’s of years later?

    The beginning of wisdom is the fear of God. And what is more glorious than Isa. 40?

    Good word Aaron. 🙂

  7. 4. To better understand Jesus Christ. When we read about the apostles and all the disciples in the New Testament (NT) we should remember that the only Bible they had was what we call the Old Testament (OT). The apostles and disciples never expressed any dissatisfaction with the OT, and certainly didn’t wait for the NT to be written in order to proclaim Christ. By the Holy Spirit, they saw Christ from one end of the Old Testament to the other. And if our English Bibles capitalize OT quotes in the NT, we can see this for ourselves. Let us therefore keep looking for Christ in the Old Testament, for that is the ultimate purpose for which it was written.
