From the post The Passion, prophecy, the pedigree of proof-texting, and a podcast
Preachers and inspirational/devotional writers make whole bales of hay out of this sort of typology and similarly anachronistic readings of the OT: our congregations are led to believe that there is christological, or at very least explicitly Christian, significance to be found in seemingly every nook and cranny of the OT. … We should keep around the Old Testament not because of an erroneous assumption that it is crypto-Christian, but precisely because it’s a testimony of what faith in God looked like before Christ. Reading the Old Testament makes me glad I’m a Christian.
