The word "rapture" in not in the Bible, true. Does that mean the rapture isn't talked about? There are literally hundreds of verses about this, here some of them.
1Th 3:11 Now may our God and Father Himself and Jesus our Lord direct our way to you;
1Th 3:12 and may the Lord cause you to increase and abound in love for one another, and for all people, just as we also do for you;
1Th 3:13 so that He may establish your hearts without blame in holiness before our God and Father at the coming of our Lord Jesus with all His saints.
1Th 4:14 For if we believe that Jesus died and rose again, even so God will bring with Him those who have fallen asleep in Jesus.
1Th 4:15 For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord, will not precede those who have fallen asleep.
1Th 4:16 For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.

2Th 2:1 Now we request you, brethren, with regard to the coming of our Lord Jesus Christ and our gathering together to Him,

2Th 2:3 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction,
2Th 2:4 who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.
2Th 2:5 Do you not remember that while I was still with you, I was telling you these things?
2Th 2:6 And you know what restrains him now, so that in his time he will be revealed.

2Th 2:8 Then that lawless one will be revealed whom the Lord will slay with the breath of His mouth and bring to an end by the appearance of His coming;
2Th 2:9 that is, the one whose coming is in accord with the activity of Satan, with all power and signs and false wonders,
