And John makes it clear that God loves the world. Not just some people who are in the world. But he has a love for everyone. And Jesus came to be the savior of everyone. And all who will believe in him will experience that salvation he offers. Those who refuse to believe will remain in this world and be condemned.
I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, and his incomparably great power for us who believe. - Ephesians 1:17-19 NIV
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work. - 2 Timothy 3:16-17 NIV
