In this chapter, Paul offers an intense and strict reminder of the predicted events of the Rapture. He warns his followers that no vehicle of instruction – no letter or prophecy – should be taken seriously if it claims that the Day of the Lord has come. The heading “the Man of Lawlessness” is indicative of Satan, who will use his deception to draw away those who follow God. This antichrist will see to it that he becomes the object of human worship. He will proclaim himself to be God (verse 4), but we should not be led astray by his appearance or influence.
The secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way. (1 Thessalonians 2:7)
Satan’s power is already at work, manifested in many different facets in our daily life, at work, university, school, and sometimes even home. We should not let down our guard, but remain vigilant to keep his deception at bay.
The doctrine of salvation establishes that:
(1) God the Father will elect and call us to be Christians.
(2) God the Son will share his glory with his People.
(3) God the Holy Spirit will impart wisdom and sanctifying grace to believers.
This is perfectly summed up by verse 16:
May our Lord Jesus Christ himself and God our Father, who loved us and by his grace gave us eternal encouragement and good hope, encourage your hearts and strengthen you in every good deed and word.
Of course, this is only made possible through partnering with God, as was emphasized in the previous chapter. Pray for the Holy Spirit to intervene when temptation strikes. Constantly remind yourself of his righteousness, faithfulness, and love to keep sin at bay. And ask for his forgiveness when you know you have sinned.
