True godliness is a gift of God by which man is made willing and able to serve God. He no longer lives according to the lust of the flesh, as the ungodly do, but according to the will of God, revealed to us in His Word. For this reason, the godly life, in which we give ourselves over to the service of God so that we live no longer for ourselves but for God, is called our reasonable service. That means we regulate our service to God according to the direction of the reasonable ‘milk’ of God’s Word, not according to our own notion or understanding (1 Peter 2:2).
– Willem Teellinck – The Path of True Godliness
Willem Teellinck, Dutch Puritan (January 4, 1579 – April 8, 1629) was one of the leaders of the Nadere Reformatie or Dutch Further Reformation. He is the author of many books, but is perhaps best known today for The Path of True Godliness, a wonderful book on the subject of Biblical, Puritan piety.
