Typology is a special kind of symbolism. A symbol is something that represents something else. We can define a type as a “prophetic symbol” because all types are representations of something yet future. More specifically, a type in Scripture is a person or thing in the Old Testament that foreshadows a person or thing in the New Testament. For example, the flood of Noah’s day (Genesis 6—7) is used as a type of baptism in 1 Peter 3:20–21. The word for “type” that Peter uses is "figure".
