The best things of life come to us wrapped up in difficulties, obstacles, seeming hindrances and oppositions, and unless we meet them heroically and victoriously we shall miss God's richest and best gifts and treasures. It is hard, for example, to have a besetting sin, one specially weak point, one temptation that comes perpetually up to us, stalking like a Goliath before us. Some of us know what it is to have sins which we do not overcome, which we do not even wrestle with, but which we allow to overcome us again and again. But do we not know that these very besetting sins are enemies that can be made friends to help us heavenward?
