As we have been going through the letter of 1 John we see him addressing the issue of sin within the church, the issue of false teaching,
and the perspective of love as a solution to sin issues within the church. He ended the discussion of love being the solution to sin issues within the church by saying this:
1 John 3:23-24
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. Those who obey his commands live in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
