21 Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, 2 not to become easily unsettled or alarmed by the teaching allegedly from us-whether by a prophecy or by word of mouth or by letter-asserting that the day of the Lord has already come.
3 Don't let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness[1] is revealed, the man doomed to destruction.
21 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
21 Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers,
3 Let no one deceive you in any way. For that day will not come, unless the rebellion comes first, and the man of lawlessness
21 Now, friends, read these next words carefully. Slow down and don't go jumping to conclusions regarding the day when our Master, Jesus Christ, will come back and we assemble to welcome him. 2 Don't let anyone shake you up or get you excited over some breathless report or rumored letter from me that the day of the Master's arrival has come and gone.
3 Don't fall for any line like that.
21 Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2 not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come.
3 Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition,
21 Now, dear brothers and sisters, let us clarify some things about the coming of our Lord Jesus Christ and how we will be gathered to meet him. 2 Don't be so easily shaken or alarmed by those who say that the day of the Lord has already begun. Don't believe them, even if they claim to have had a spiritual vision, a revelation, or a letter supposedly from us.
3 Don't be fooled by what they say. For that day will not come until there is a great rebellion against God and the man of lawlessness is revealed-the one who brings destruction.
Matthew Henry's Commentary on 2 Thessalonians 2:1-3
Commentary on 2 Thessalonians 2:1-4
(Read 2 Thessalonians 2:1-4)
If errors arise among Christians, we should set them right; and good men will be careful to suppress errors which rise from mistaking their words and actions. We have a cunning adversary, who watches to do mischief, and will promote errors, even by the words of Scripture. Whatever uncertainty we are in, or whatever mistakes may arise about the time of Christ's coming, that coming itself is certain. This has been the faith and hope of all Christians, in all ages of the church; it was the faith and hope of the Old Testament saints. All believers shall be gathered together to Christ, to be with him, and to be happy in his presence for ever. We should firmly believe the second coming of Christ; but there was danger lest the Thessalonians, being mistaken as to the time, should question the truth or certainty of the thing itself. False doctrines are like the winds that toss the water to and fro; and they unsettle the minds of men, which are as unstable as water. It is enough for us to know that our Lord will come, and will gather all his saints unto him. A reason why they should not expect the coming of Christ, as at hand, is given. There would be a general falling away first, such as would occasion the rise of antichrist, that man of sin. There have been great disputes who or what is intended by this man of sin and son of perdition. The man of sin not only practises wickedness, but also promotes and commands sin and wickedness in others; and is the son of perdition, because he is devoted to certain destruction, and is the instrument to destroy many others, both in soul and body. As God was in the temple of old, and worshipped there, and is in and with his church now; so the antichrist here mentioned, is a usurper of God's authority in the Christian church, who claims Divine honours.
