In this life, they have their fill of good and comfort. They haven’t experienced pain or awful things that make them cringe therefore they have no need to long for a new Heaven and a new Earth. They need not long for Christ’s return because there’s no yearning in their heart for justice to be served in their lives or in the lives of others. It’s hard to believe but there are many self-proclaimed Christians who live with such a mindset. Christ’s return is a hindrance for them, it cuts their plans short. They want to experience more of this life. They’ve become attached to the world, “coming out from among them” has no meaning for them.
