What world is John speaking of? → The earth and all the people born into humanity.
The Holy Spirit is love and love is of the Holy Spirit.
The world was created by our Lord and it is good. We know that man chose rebellion against the Holy Spirit and so humanity became evil. But the Holy Spirit loves the people of this world and so He birthed Christ Jesus into the world to redeem it and us.
The Gospel is heard and those who are hungry are lead by the Holy Spirit to believe and receive the Truth.
The Truth sets us free from sin, from death and hell and brings us to Eternal Life by the infilling of the Holy Spirit.
Here is understanding: → Everlasting Life is Eternal Life → Eternal Life is union with the Holy Spirit.
But the Lord loves us and desires for us to be saved - to experience eternal, abundant life.
We see that the nature of the Holy Spirit is love and Grace. That nature manifested itself in the Lord Jesus Christ who legitimized that Grace.
" Grace is a person and His name is Jesus." - Joseph Prince
But we understand that Jesus was begotten of His Holy Spirit and is the verbal and physical expression of His Holy Spirit.
