1 Thessalonians 1:10
And to wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come.
The Thessalonians waiting for Jesus to return from heaven implies the possibility of His coming during their lifetime. The imminent, which means impending, near, close, immediate, return of Jesus is our hope. Jesus may come at any moment and we are to be prepared. The coming of Jesus for His people, can be understood in two ways – 1) He delivers us from the eternal punishment of our sins, 2) He delivers us from the coming period of judgment, when the wrath of God will be poured out on the world that has rejected His Son.
