We not only can't know the day or the hour of Jesus' return, Mark 13:32, we can't know when the time is too, Mark 13:33. Not only that we can't even know for sure that we are even in the season, Acts 1:7. I don't believe this contradicts when He says when we see certain things happening to look up that our redemption draws near either as we are to be ready at any time but regardless, we are to take the gospel everywhere, Acts 1:8. Consider that on any given day someone could die and leave this earth regardless if Jesus comes back now or later and that person would have to face his or her maker. So spreading the gospel is the paramount issue anyway as without the gospel, none of it means anything.
