1John2:9-17 are addressing those who make the claim of accepting The Gospel of Jesus Christ as their only source of Eternal Security!

(I copied this “definition” of The Gospel from gotquestions.org ,”The gospel of Jesus Christ is the good news that God provided the way for mankind to be freed from the penalty of sin (John 14:6; Romans 6:23). Everyone dies physically, but those who believe in Jesus Christ are promised a physical resurrection unto eternal life (John 11:23–26). Those who reject Christ will not only die physically but will undergo a “second death,” which the Bible describes as an eternal lake of fire (Revelation 20:13–14). Jesus is the only One in whom salvation can be found (Acts 4:12).)The verses in 1John2:9-17 describe what a life that has sincerely turned to a new life into The Light of The Gospel will look like.God gives us these verses so we can do at least 2 things.One is for us to have the help of HIS Word in identifying those who are sincere in their “life-trust” in The Gospel of Jesus Christ and those who more than likely are not.The other purpose is for those who are sincere in their Faith in The Gospel of Jesus Christ to have The Guiding Light of God’s Word to keep us from veering away from the new life that Jesus Christ gives us through His Gospel.In verses 15-17 of this section,God gives us the simple guide for those living in His Light,and not the darkness of the world- “Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them.For everything in the world-the lust of the flesh, the lust of the eyes, and the pride of life-comes not from the Father but from the world.The world and its desires pass away, but whoever does the will of God lives forever.”.When John talks about “the world”,he isn't referring to the physical sphere we call Earth. Rather, it's a system of thought, motivation and ideas. "Love" should define Christians in their relationship with God and each other. "Lust" characterizes people imbued with the spirit of the world and the demonic forces that shape it.John names three lusts that govern the world.Putting riches before God is the lust of the eyes, which is materialism or coveting. A desire to be famous is the pride of life. The third, lust of the flesh, refers to sinful sensual pleasure. God created sensual pleasure to be enjoyed by a man and a woman within the confines of marriage, but sex outside marriage is driven by lust, not love.Boil down is that our lives are defined by what&/or who we love,that is why this section of Scripture starts out with “Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them.”The WHO and WHAT we love are the ultimate determining factors of whether or not we have sincerely taken the gifts of The Gospel of Christ as our own or not.This doesn’t mean that we all have an overnight night&day transformation when we decide to Trust Christ! It does mean that our lives will bare witness to THE LIGHT of The Gospel of Jesus Christ becoming an ever increasing guiding LIGHT for our lives as we dedicate our lives to the pilgrimage of being one that lives in The Light of The Gospel of Jesus Christ.Dear Lord,not only does my life not always indicate my living in Your Light,but my motivations and thoughts fail miserably much of the time.I praise You for Your patience & persistence & perseverance with me...and I pray for Your Spirit to help me have more life&motive&thought steps today that are in Your Light!
