If the world is not rooted out from our hearts, it will devour them. There must be weeding, if the good seed of grace is to grow. But what weed-killer can we use against the spirit of the world? Here is a potent, three-fold formula from the Bible: 1. Recognize that love of the world is the enemy of the love of the Father (1 John 2:15). You cannot have both. You must choose one only. Make the right choice. 2. Remember that it was the world that crucified Christ and that it took the sacrifice of the Cross to deliver you from it (Gal. 6:14). How can you negotiate with the spirit which plotted the assassination of your Savior? 3. Reflect on the fact that the world, in this sense, is transient and ephemeral (1 John 2:17); it is not a solid investment. Devote yourself instead to having “treasure in heaven” (Matt. 6:19-21).
