It's not a trivial matter. It's not futile or vain. It's worth taking time, spending time, and even losing time to do it. Every single time a person shares the gospel with another person, it is an act of love. Those moments are valuable, and priceless. They are filled with eternal consequence.
Oh, that we would grasp its significance every waking moment as we go about our daily schedules, and follow our weekly planners. selahV
