What does 1 Thessalonians 1:10 mean?
Paul reports that the Thessalonian Christians had turned to God, from idols (1 Thessalonians 1:9). They not only worked to serve the living and true God, but also "to wait for his Son from heaven."Forty days after rising from the dead Jesus ascended to heaven, where He sits on the right side of the Father (Mark 16:19; Acts 1:9–11; Romans 8:34; Ephesians 1:20). The Thessalonians were aware that He promised to return, and they were eagerly anticipating that day.
Before He died on the cross, rose again, and returned to heaven, Jesus urged His disciples not to be troubled. He described heaven as His Father's house with many rooms and assured them He was going there to prepare a place for them. Then He added the bright prospect of His return: "And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also" (John 14:3).
This same Jesus rescues us from the wrath of God that will fall on all who reject His Son (John 3:36; Revelation 20:10–15). In addition, He will pour out His wrath on the earth during the tribulation, the seven-year period that follows Jesus' return for the church (Revelation 6:16–17). Later in this same letter, Paul will expound on the way this eventual return will play out.
