1 Thess 1:10, James 5:8-9, 1 Pt 4:7, 1 Jn 2:18, 1 Cor 7:29-31, Rev 22:20
The early church members waited for Jesus to come back while they were still alive. (1 Cor 1:7, 1 Thess 1:10)
1 Cor 1:7 So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:
1 Thess 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 apostles also said that the coming of Jesus Christ was near. (James 5:8-9, 1 Pt 4:7, 1 Jn 2:18, 1 Cor 7:29-31)
James 5:8 Be ye also patient; stablish your hearts: for the coming of the Lord draweth nigh. 9 Grudge not one against another, brethren, lest ye be condemned: behold, the judge standeth before the door.
1 Pt 4:7 But the end of all things is at hand: be ye therefore sober, and watch unto prayer.
1 Jn 2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
1 Cor 7:29 But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none; 30 And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not; 31 And they that use this world, as not abusing it: for the fashion of this world passeth away.
Jesus also promised that He would come soon. (Rev 22:20)
Rev 22:20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
