Life is busy. There are daily concerns and obligations that have to be met, and to take time to think about how precious and special a human life is that you only get one, and that every wasted minute is lost. You can't get it back.
The church must seek to be biblical rather than relevant. We are not going to leave a mark upon our culture because we have studied its ways and adapted ourselves to it. We are relevant when we reject the world outright and are its polar opposite! This present darkness provides a great opportunity for the church to be the salt of the earth, but if we mix with the very impurities we are supposed to expose. . . we are as useless as our culture already believes us to be.
