And He will send out His angels and gather His elect [i.e., God’s people] from all directions, from the farthest part of the earth to the farthest part of the sky [i.e., from throughout the whole world].
And He will send out His angels [i.e., as messengers] with the sound of a great trumpet [See I Thess. 4:16] to gather His elect [i.e., God’s people] from all directions, [even] from throughout the whole world. [Note: See Mark 13:27, which suggests this thought by its use of ‘earth’ and ‘sky’]
In the presence of God and of Christ Jesus, who will judge [both] those still alive and those who have already died, and in view of His appearing [i.e., at His second coming] and His kingdom [i.e., when it is revealed in its eternal splendor], I solemnly urge you:
May the Lord strengthen your hearts so you will be [found] without just blame and holy, in the presence of our God and Father, when our Lord Jesus Christ returns with all of His holy ones [i.e., angels. See Mark 8:38; II Thess. 1:7].
For what is [the basis of] our hope, or joy, or crown of honor in the presence of the Lord Jesus when He comes back? [Note: By “crown” Paul alludes to the laurel wreath awarded to the victor in an athletic contest]. Will it not be you people?
And people from all the nations will be assembled in front of Him and He will separate them from one another, like a shepherd separating his sheep from the goats.
[He did this] to fulfill His plan at the proper time, by bringing together everything [in the universe] under Christ’s headship --- things both in heaven and on earth.
So, I urge you, brothers, because God is so merciful [to us], to offer your bodies as a living sacrifice, [fully] dedicated and very pleasing to God. For this is a reasonable [or spiritual] way for you to worship [or serve] Him.
For the Son of man will return in the splendor of His Father, accompanied by His angels. Then He will reward or punish every person in proportion to what he has done [with his life].
Finally then, brothers, we request and urge you, in [the fellowship of] the Lord, that you should live [dedicated lives] and please God. Just as you people received direction from us [on doing this], see that you [continue to] do it more and more.
We ought to thank God for you always, brothers, since it is proper, because your faith is growing so much and the love that every one of you has for each other is increasing more and more.
