"In order to men's being true Christians, it is necessary that they prosecute the business of religion, and the service of God, with great earnestness and diligence, as the work to which they devote themselves, and make the main business of their lives. All Christ's
peculiar people, not only do good works, but are
zealous of good works, Tit. ii. 14. No man can do the service of two masters at once. They who are God's true servants, give up themselves to his service, and make it as it were their whole work, therein employing their whole hearts, and the chief of their strength; Phil. iii. 13. " This one thing I do." Christians in their effectual calling, are not called to idleness, but to labour in God's vineyard, and spend their day in doing a great and laborious service. All true Christians comply with this call, (as is implied in its being an effectual call,) and do the work of Christians; which is every where in the New Testament compared to those exercises, wherein men are wont to exert their strength with the greatest earnestness, as running, wrestling, fighting. All true Christians are good and faithful soldiers of Jesus Christ, and
fight the good fight of faith: for none but those who do so,
ever lay hold on eternal life. -Those who
fight at those who beat the air, never win the crown of victory."
Jonathan Edwards
