In a sermon based on Genesis 5:24 (‘And Enoch walked with God’) Whitefield, in seeking to explain how the child of God receives guidance, wrote the following:
‘In order to walk closely with God, his children must not only watch the motions of God’s providence without them, but the motions also of his blessed Spirit in their hearts.
‘As many as are the sons of God, are led by the Spirit of God’ (Romans 8:14), and give up themselves to be guided by the Holy Ghost, as a little child gives its hand to be led by a nurse or parent.
‘It is no doubt in this sense that we are to be converted, and become like little children. And though it is the quintessence of enthusiasm, to pretend to be guided by the Spirit without the written word; yet it is every Christian’s bounden duty to be guided by the Spirit in conjunction with the written word of God.
Led by the Spirit and guided by the Word‘Watch, therefore, I pray you, O believers, the motions of God’s blessed Spirit in your souls, and always try the suggestions or impressions that you may at any time feel, by the unerring rule of God’s most holy word: and if they are not found to be agreeable to that, reject them as diabolical and delusive.
By observing this caution, you will steer a middle course between the two dangerous extremes many of this generation are in danger of running into; I mean, enthusiasm on the one hand, and…downright infidelity on the other.’
