John concludes his letter saying believers can have confidence about three things: 1) that you have eternal life, 2) that your sin cannot jeopardize that life and 3) that this gospel message is true.
John tells us genuine believers will confess that Jesus is the Christ — the Jesus who was confirmed by three witnesses: “water”, “blood” and “the Spirit.”
In 1 John 4:7-19, John explains why self-sacrificing love is a mark of a believer: this other-focused love is part of God’s holy character and God is in the process of giving us His character.
The Apostle John says we can identify false prophets two ways: by the content of what they say (4:2) and by the origin of what they say (4:6).
How can John say that love is a mark of believers and hate is a mark of non-believers when we know believers who struggle with hate and non-believers who genuinely love others?
