We are also called to be the Salt of the Earth. Salt is a preserving agent but it also makes one thirsty. When we are caught up to be with Christ in the clouds the preserving agent of this world will be gone. The time for us to cause the lost to thirst is now. Now is the time. Today is the day.
I encourage you to read this book. It will change your life. It will create an urgency of the day and hour in which we live.
