Eschatology is defined by Merriam Webster's Collegiate Dictionary (Tenth Edition) as, "the branch of theology concerned with the final events in the history of the world or of mankind."
I think this subject is important to study. Jesus Christ, the King of Kings and Lord of Lords (1 Timothy 6:15, Revelation 19:16), talked about it at length when asked in Matthew 24:3 and Luke 21:7. Paul writes about it in 1 Corinthians 15, as well as in 1 and 2 Thessalonians. Remember that in writing to his "children" (1 Timothy 1:2, 2 Timothy 1:2, Titus 1:4), Paul emphasized the importance of solid teaching/doctrine (1 Timothy 4:6, 16, Titus 1:9, 2:1, 7, 10).
Eschatology helps us grasp with our minds and hearts the future of the redeemed and the lost - the severity of eternity spent in God's gracious love or His unrelenting wrath. We can be encouraged by the fact that He Himself is the protection for the Church, His bride, both now and in the future. Truly grasping the depth of this subject will help you long for His return.
So, if these statements are true, why do some Christians shy away from the topic? I will give three possible reasons:
1) Perhaps there is a belief that some or all of the events in the future are unknowable. I call this idea, "Prophetic Agnosticism." This concept could stem from a belief that God does not know all things or from a hesitancy to make authoritative conclusions derived from prophetic books such as Daniel, Ezekiel, Zechariah and Revelation.
While I believe that God is omniscient, I do understand the hesitancy. Prophetic books have a lot of passages that require careful interpretation. Jesus Christ, in speaking of His return, says in Matthew 24:36 and Mark 13:32 that only the Father knows the hour and day (Note to Christians: if you ever hear anyone claiming to have knowledge of the specific day and hour of Christ's return, respectfully challenge them with these verses).
While I respect the hesitancy, I do not believe that all we can safely conclude about the future is that Christ will return. We have too much of the Word of God detailing this subject to be THAT restrictive in our eschatology deductions.
2) I think many Christians shy away from this topic because it causes controversy. Undoubtedly, many pointless arguments and disputes that do not exalt Jesus Christ have been waged over this topic. These type of engagements within the Church do
not serve as a good witness to unbelievers.
However, the fact that a pariticular topic is controversial should not, by itself, deter Christians from an honest study of the topic. For example, soteriology (the theology of salvation) is a controversial topic, but Christians MUST have a right understanding and heart belief in the truth that we are justified by grace through faith (Romans 4:5-6, Galatians 2:20-21, Ephesians 2:8-9, Titus 3:5-7, to name a few).
Eschatology is
not salvific (meaning that it does
not have the power to save anyone from their sins), but it is a branch of theology that helps us understand our Master and His plans for Himself, the world and its inhabitants. Therefore, we should not shy away from this topic, but rather study it, pray about it, and dialogue about it with others in an honest, yet peaceable manner.
3) Third, and perhaps the strongest reason I can think of for a lack of knowledge among Christians regarding eschatology, is a perception that eschatology is not an important topic to study. Hopefully, this post has convinced you otherwise!
I think that a one-on-one or small group conversation is a suitable forum for a fuller discussion of the topic, so let me know if you ever want to converse with me about eschatology.
