Many Christians have used 1 John 5:13 to give doubting believers the assurance of their salvation. John says that he wrote “these things” that we may know that we have eternal life. But what are “these things”? This commentary examines the three major tests or evidences of salvation delineated by the Apostle John. These things are the doctrinal test, the social test, and the moral test. Do I believe the right things? Do I love my brother? Is my life characterized by righteousness? In short, does my life give evidence that I have been born again? Do I pass the tests? If we were ever arrested for being a Christian, there ought to be enough evidence to convict us. The epistle of 1 John is written to help explain these evidences.
