Teaching that Jesus can return anytime promotes readiness and faithfulness in those who desire to make themselves ready. The Lord commanded us to makes ourselves ready and pray we escape the all of these things that were to come to pass:
Lk 21:36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
Let's look at what He told promised the church of Philadelphia :
Rv 3:10 Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
I am seeing more and more a promise of deliverance for those that have first love for Jesus and follow Him fully.
