Some theologians argue against the imminent return of Christ being taught in the Bible. They say that Christ promised Peter he would live to an old age (GJohn 21.18, 19) and therefore Christ could not have returned until Peter was old. For the early church that precluded an any-moment Rapture.
However, Peter himself told believers to look for the coming of the Lord, calling those who did not do so willingly ignorant (2 Pt 3.3-5).
When John wrote the Gospel, and said Peter was to live to be an old man, Peter was already dead 20 years or more ago. So, by the time this saying of Jesus (in the Gospel) was sent out to the churches, they would not have argued this saying. Who knows how old Peter was when he died (under Nero's reign) or what constitutes "old" man.
Essentially, this argument no longer has any force.
