Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak (Matt. 26:41). These words, which Jesus spoke to his disciples in the garden of Gethsemane, serve as the foundation for John Owen’s treatise Of Temptation. Owen preached on the subject of temptation frequently during his many years of service as the dean and vice chancellor of Christ Church in Oxford–Of Temptation is the culmination of his discourses on the subject. In his treatise, Owen addresses the nature and power of temptation, the risk of entering into it, and the means of avoiding its danger. Owen defines temptation as anything with the ability to entice the Christian’s mind or heart away from obedience to God and redirect it towards sin. Owen warns us that our power is not strong enough to protect us from temptation; rather, it is by God’s power of preservation that we are saved. As Christians, we can guard ourselves against temptation in part by praying for God’s power to help us resist it. His treatise teaches Christians how to recognize the threat of temptation and protect themselves against it.
