'Time' in the Bible

The religious service which is pure and stainless in the sight of our God and Father is to visit fatherless children and widowed women in their time of trouble, and to keep one's own self unspotted from the world.

when, all the while, you do not even know what will happen to-morrow. For what is the nature of your life? Why, it is but a mist, which appears for a short time and then is seen no more.
