If the soul be at rest with God, it is of little consequence where the body rests.

This was the reward of his services, the effect of his extraordinary meekness. There was solemn mourning for him. Yet how great soever our losses have been, we must not give ourselves up to sorrow. If we hope to go to heaven rejoicing, why should we go to the grave mourning? |
