John Newton wrote many pastoral letters in his lifetime. He was uniquely gifted by God to encourage his recipients so long ago, and still encourage those who read from his hand today. This is an excerpt from one such letter to Captain Alexander Clunie in 1766 about the delusions that Satan seeks to use on those in this world:
The good Lord keeps us from his delusions; he is always dangerous, but never more so when he pleads for Gospel doctrines in order to abuse them, and when he tries to pass his counterfeit humility, zeal, and sanctity upon us for pure gold. No coiner can equal him for imitation. Where Christ has a church, he will have a synagogue; where the Spirit produces any graces, he, like the magicians of Egypt, will do something like it, and yet as unlike it, as possible. He has something that comes so near the Gospel, that it is called by St. Paul another gospel, and yet in reality it is no gospel at all. He deals much in half convictions, and almost Christians, but does not like thorough work. He will let people talk about grace as much as they please, and commend them for it, provided talking will satisfy them...But, let him look and talk as he desires--he is Satan still; and those who are experienced and watchful may discern his cloven foot hanging below his fine garment of light! He is never more a devil--than when he looks most like an angel. Let us beware of him; for many wise have been deceived, and many strong have been cast down by him. Let us continually apply to him who is able to keep us from falling, and to present us spotless in the end.
