1Thessalonians 2:1 For yourselves, brethren, know our entrance in unto you, that it was not in vain
‘Know our entrance in unto you’ – Twelve times he called attention to the Thessalonians showing what they know of truth: Know what manner of men we were (1:5). Know our entrance unto you (2:1). Know how shamefully we were treated (2:2). Know we did not use flattering language and were not covetous (2:5). Know how we exhorted, comforted, and charged you (2:11). Know that we were appointed afflictions for the gospel (3:3-4). Know what commandments we gave you by Jesus Christ (4:2). Know how to possess your vessels in sanctification and honour (4:4). Know perfectly about the day of the Lord (5:2). Know your true teachers (5:12). Know what withholds that the Antichrist might be revealed (2Thess. 2:6-8). Know how you ought to follow us (2Thess. 3:7).
Note the twelve “Know You Not’s:” That so many of us as were baptized into Jesus Christ were baptized into His death (Rom. 6:3)? That to whom you yield yourselves servants to obey, his servants you are – sin or righteousness; satan or God (Rom. 6:16)? That I speak to them that know the law – the Jews (Rom. 7:1; cp. 1Thess. 2:12-16)? That you are the temple of God, and that the Spirit of God dwells in you (1Cor. 3:16)? That a little leaven leavens the whole lump (1Cor. 5:6)? That saints shall judge the world (1Cor. 6:2)? That saints shall judge angels (1Cor. 6:3)? That the unrighteous shall not inherit the kingdom of God (1Cor. 6:9)? That your bodies are members of Christ (1Cor. 6:15)? That he which is joined to a harlot is one body (1Cor. 6:16)? That your body is the temple of the Holy Spirit (1Cor. 6:19-20)? That they which run in a race all run, but only one wins the prize (1Cor. 9:24)?
‘That it was not in vain’ – A steadfast congregation was established (Acts 17:1-34).
