Typology, the teaching that the Old Testament prefigured events in the New Testament is an important concept to understand as you read your Bible. It’s important because when we see how God has worked out the same plan for salvation history over thousands of years it can give us hope and confidence in our faith and trust in the future God has prepared for us. He did that by showing a type (a preview) of an important truth in the past, that was later fulfilled in reality in the future.
For example, one of the most well-known examples of typology is that in the Old Testament, they sacrificed lambs because of people’s sins. But offering them only covered up their sin until Jesus came to be the final sacrifice and eternally took away our sins. The video that follows will help explain this in more detail.
