3 We are bound to thank God always for you, brethren, as it is fitting, because your faith grows exceedingly, and the love of every one of you all abounds toward each other, 4 so that we ourselves boast of you among the churches of God for your patience and faith in all your persecutions and tribulations that you endure, 5 which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer; 6 since it is a righteous thing with God to repay with tribulation those who trouble you, 7 and to give you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels (2 Thessalonians 1:3–7, NKJV)
What a magnificent summary of the Thessalonian saints’ faithfulness in the face of persecution, of their tremendous example of suffering for the kingdom and its powerful influence on brethren, and of God’s justice that trouble the troublers and rewards the faithful with rest. God is righteous; therefore, so is His judgment. In the glory of Christ returns, God will right every wrong leveled against His people (2 Thess. 1:8-10). Until then, keep patiently enduring in faith and love. God sees, He repays, and He and rewards.
11 “For whoever exalts himself will be humbled, and he who humbles himself will be exalted.” 12 Then He also said to him who invited Him, “When you give a dinner or a supper, do not ask your friends, your brothers, your relatives, nor rich neighbors, lest they also invite you back, and you be repaid. 13 But when you give a feast, invite the poor, the maimed, the lame, the blind. 14 And you will be blessed, because they cannot repay you; for you shall be repaid at the resurrection of the just.” (Luke 14:11–14, NKJV)
Jesus, the Son of God, was humble. He lowered Himself, humbled Himself, to help the helpless, to save His enemies – sinners, like you and me. We are not humble when we only bless those who can repay us. Such conceit arrogantly judges others as it says, “I will only treat you nicely because I expect you to be nice to me in return.” That is not loving, merciful, or the attitude of God (Matt. 5:43-48). Reciprocity is not the Christian’s motivation for being kind and pleasant. The gospel goes out to all, and we must try to bless all with whom we have contact, trying to save some (Rom. 12:17-21). So, keep and show godly attitudes, even toward those who mistreat you (Matt. 5:10-12). Always treat others kindly, even when they are not kind toward you (Matt. 7:12). The Lord will repay you at the resurrection (Jno. 5:28-29). That will be enough.
