The Lord calls us to be active, pro-active, and zealous in working for Him (see Heb 6:10-12). The love of Christ impels us (2 Cor 5:14) to work harder for Jesus than any multi-millionaire ever worked to make His businesses more profitable. However, many Christians are not working much for the Lord. The harvest is great, but the workers always seem so few (Mt 9:37). What's the problem?
Christians are motivated and energized by love. To do God's work, we must possess God's love. When we stop loving, we stop working. In the midst of our work, we run into difficulties, persecutions, and enemies. We naturally feel like hating and retaliating. However, the Lord calls us to love our enemies actively and pro-actively. We are to offer them our other cheek, hand over our coats, and go the extra mile with our enemies (Mt 5:39-41). When we love our enemies like this, then the more enemies we have, the more work we do for Jesus. No enemy can stop God's work, but our refusal to accept the grace to love our enemies will certainly stop God's work. There are few workers in God's harvest because few people love their enemies.
St. Benedict said: "Pray and work." The Lord says: "Love and work." We should love especially our enemies, and pray and work for their salvation.
