Our eyes wait upon the LORD our God, until that he have mercy upon us. No man is an island to himself.
Man is a gregarious animal, like sheep gathering into a flock.
Nor can a Christian thrive without fellowship with another Christian. So, also it is with the sacred bond of marriage. Thus, when Joshua wanted to know the condition of Jericho which he was going to conquer, he sent two spies to do the job. Jesus sent seventy preachers, but two by two, that they might be a help one to another. This refers to the mutual warmth between husband and wife in a cold wintry night.
