Eschatology is the branch of systematic theology that deals with the second coming of Christ, resurrection, judgment, the end of the world, and eternity. We know that -ology means a study of, and the Greek word eschatos means last. The word eschatology is a study of last things. Eschatos is translated last 46 times in the King James Version of the New Testament. Sometimes it is contrasted with first. For example, see Matthew 19:30; 20:16; 27:64. It is frequently used with day or days. Some references are John 6:39, 40; 11:24; Acts 2:17; 2 Timothy 3:1.
In our study of eschatology we are not going to limit ourselves to the study of the last days. Instead, we will take a broad look at predictive Scriptures. In other words, eschatology to us will be the study of Bible prophecy.
