Can you find the plan of salvation or the Gospel in Exodus or the Old Testament?
No, the plan of salvation is not found in Exodus or anywhere else in the Old Testament; only a picture of it appears there. The Old Testament was written for our learning, not our doctrine, so that through patience and comfort of the Scriptures we might have hope.
Les explains from Romans 15:4 that Paul, writing to the Christians at Rome, says whatsoever things were written aforetime—back in the Old Testament—were written for our learning. Genesis, Exodus, and Leviticus were written to the Jew under the Law, yet they are for our learning. Les warns that many today shut their eyes to the Old Testament thinking it has nothing to do with them, but it is a bedrock for the New, and the New cannot be understood without the Old. Paul does not say these things are our doctrine. You will not find the plan of salvation back in Exodus; you will find a picture of it, but not the Gospel in Exodus or anywhere else in the Old Testament. It is there so that through patience and comfort of the Scriptures we might have hope.
