Ephesians 1:17 says:
“That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of Him: The eyes of your understanding being enlightened; that you may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints.”
Now, the hope of our calling according to Paul’s letter to the Colossians is Christ in us. Hence, the essence of our salvation and calling is to be conformed to the image of Christ. (Colossians 1:27).
The present heaven and earth will pass away according to II Pet 3:10. And, it’s obvious that we’ve not been called unto something that will pass away. God foreknew us and called us so we can be justified and ultimately glorified.
Jesus said in the gospel of John “if a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode (dwelling place) in him.” So God who is in heaven desire to make man his dwelling place that is what he promised us in Isaiah 66:1.
If God is desirous of leaving heaven and wants to ultimately destroy it, it is obvious it cannot be the hope of our calling.
The hope of our calling starts with Christ been formed in us and ultimately God dwelling in us. This is a promised given us even before the world began as seen in Titus 1:2. Here, it is called the hope of eternal life which God who cannot lie promised before the world began.
Therefore, in the light of God’s Word, the hope of our calling is not heaven. We are called to learn and conform to the image of Christ and ultimately inherit God.
God bless you!
