When we see what is in Heavenly Places our hearts are forever oriented toward Him who fills heaven and earth with His glory. carnality is base and has lost its appeal.
The glory of Christ is what He willed and accomplished for us by enduring the cross and raising Himself from the dead - sonship in the New Birth by His Holy Spirit as joint heirs of all that the Father has.
What world is John talking about? He is talking about the people on earth who are Carnal Minded having never received the Gospel of Jesus Christ.
Those who are Carnal Minded cannot understand those who have become Spiritual Minded by receiving the Truth and being Born Again.
The Father is the Holy Spirit Of Christ Jesus.
For a person to love the Father is to love His manifestation in Word and deed - Christ Jesus. ➛ His promises ➛ His sacrifice ➛ His gift of Himself
Those who selfishly and foolishly disrespect the Giver of existence, the Giver of forgiveness and the Giver of Eternal Life condemn themselves to the Lake Of Fire.
But those who honor their Creator and respond to their Saviour's love receive the King and His Kingdom.
