The Apostle John states the purpose in writing 1 John: “I write these things to you who believe in the name of the Son of God that you may know that you have eternal life” (1 John 5:13, ESV). So how do I know? What are the marks of a saved person? John’s letter provides answers.
What direction am I headed? Am I walking in the light? Read 1 John 1:5-10. It’s not that I bounce from the saved category to the lost category to the saved category with each sin and confession of sin, and I just hope that I die in the saved category. God is looking at my lifestyle–the general trend and direction of my life. This does not deny the possibility of going the wrong direction and being lost. Rather, it keeps us from going to the opposite extreme and losing any sense of Christian security.
Do I acknowledge sin in my life? Read 1 John 1:9. John is talking about a lifestyle that is willing to own up to sin–a lifestyle that listens to the correction given it by the Word.
Can I honestly characterize my life as obedient? Read 1 John 2:1-6, 2:29. We won’t be perfectly obedient, but there still ought to be a reality to our claim of obedience.
Do I love my brothers and sisters? Read 1 John 2:7-11, 3:16-24, 4:7-21. Certainly one important example of our obedience is loving our brothers and sisters.
Where are my priorities? Read 1 John 15-17. Does God come first or the world?
Do I acknowledge Jesus as the Christ, God’s incarnate Son in all I say and do? Read 1 John 2:18-24, 4:1-6, 5:1-12. The false teachers of John’s day were denying that the Son of God became flesh, dwelt among us, died on the cross, and was raised from the dead.
Do I abide in the apostolic teaching? Read 1 John 4:1-6. The “us” of this verse is the apostles. The false teachers of John’s day were not abiding by apostolic teaching. Note also the “we” of 1:1-4 and the “us” of 1:3.
Am I practicing sin or am I practicing righteousness? Read 1 John 3:1-12.
Is the Holy Spirit at work in my life? Read 1 John 2:25-29, 3:24, 4:1-6. Is the fruit of the Spirit being produced in my life (see Galatians 5:16-26)?
