1 Corinthians 15:52 says the resurrection of those who belong to christ happens at the sounding of the last trumpet. Matthew 24:29-31 indicates that a great trumpet will sound at the time of Jesus' coming after the great tribulation. Logically, then, the last trumpet cannot sound before the great tribulation (because it wouldn't be the last trumpet, since a trumpet is to sound after the great tribulation) and therefore the resurrection of the anointed cannot occur before the great tribulation. The Watchtower teaching that the resurrection of the anointed already started around 1918, is thus proven to be false.
2 Peter 3:9 indicates that God is patient in bringing the promised presence because he is giving time for all to repent because he doesn't desire any to be destroyed. This clearly implies that when the presence begins there would not be any time to repent because it will begin destructively - not as a century of invisible rule from heaven, as the JWs falsely teach. 2 Peter chapter 3 repeatedly uses "presence" and "the day of the Lord (Jehovah, NWT)" interchangeably thus demonstrating that the presence starts dramatically with the destructive day of Jehovah and not as a century of invisible rule from heaven. The idea that the presence already started in 1914 and yet there has still been a whole century of time for people to repent, contradicts what is clearly implied by 2 Peter 3:9. Note, also, that according to JW theology which holds the start of the presence to be synonymous with the start of the last days, the ridiculers mentioned in 2 Peter 3:4 would be asking where is the presence while living during the presence, and this great irony is lost to the inspired writer, Peter. Clearly, the JWs are teaching rubbish.
James 5:7 tells christians to exercise patience until the presence of Jesus. This use of until implies that when the presence starts christians would no longer need to exercise patience because at that time they will at last experience deliverance from their trials by receiving their heavenly reward. (2 Thessalonians 2:1) But according to JW theology a christian who was alive when the presence started in 1914 would have to continue exercising patience throughout his life - for a whole century! - after the presence begun. JW theology invalidates the encouragement given at James 5:7.
1914 has royally screwed up the JWs eschatology.
