Studies of the End
The word “escatology” is built from “eschata” and “logos” and means words about, or study of, the farthest or last of something. Popularly, it is teaching about “end times” of the earth. Eschata was a form of the word Jesus used to say the first would be last and the last would be first.
In its “last days” form of usage, eschatology is the various sets of beliefs regarding the destruction of the world, judgment of men and angels, and the return of Jesus to the earth, among other important ideas. What you believe regarding those ideas will control how motivated you are and what works you are motivated for in your life.
If you are convinced that your responsibility in the earth is to try to avoid sinning long enough to get raptured away from troubles and evils, you won’t be motivated to build much or to plant many trees.
If you are convinced that your responsibility in the earth is to fulfil the initial instructions to humanity of subduing the earth under the authority you have been given by the earth’s Creator, you will be building structures and systems that manifest the Kingship of Jesus, influencing cultures to submit to His power and His love, and you will be planting things that take a decade or two to bear shade or fruit.
