The Choice of Companions

We should choose the society most favorable to our spiritual advancement, and avail ourselves of every help within our reach; for Satan will oppose many hindrances to make our progress toward heaven as difficult as possible. We may be placed in trying positions, for many cannot have their surroundings what they would; but we should not voluntarily expose ourselves to influences that are unfavorable to the formation of Christian character. When duty calls us to do this, we should be doubly watchful and prayerful, that, through the grace of Christ, we may stand uncorrupted.
Lot chose Sodom as a place of residence because he looked more to the temporal advantages he would gain than to the moral influences that would surround himself and his family. What did he gain so far as the things of this world are concerned? His possessions were destroyed, part of his children perished in the destruction of that wicked city, his wife was turned to a pillar of salt by the way, and he himself was saved "so as by fire." Nor did the evil results of his selfish choice end here; but the moral corruption of the place was so interwoven with the character of his children that they could not distinguish between good and evil, sin and righteousness.
