Paul’s Prayer for the Church that the saints may see the hope of His calling
Ephesian 1:17 that the God of our Lord Jesus Christ, the Father of glory, may give to you the spirit of wisdom and revelation in the knowledge of Him, 18 the eyes of your understanding being enlightened; that you may know what is the hope of His calling,
The big word here is “See the Hope”. There is a lot of hope in His calling, we just need a spirit of wisdom and revelation to see it. Revelation is something that has been covered up and now is revealed.
Even in Revelation 1:1 it says “The revelation of Jesus Christ..” so revelation is needed to see Christ. And here the Holy Spirit helps us to understand the Word of God.
1 Cor 2:9-10 9 But as it is written: “Eye has not seen, nor ear heard, Nor have entered into the heart of man The things which God has prepared for those who love Him.” 10 But God has revealed [them] to us through His Spirit. For the Spirit searches all things, yes, the deep things of God.
The Holy Spirit illuminates us so we can get supernatural information. Paul wants us to receive divine information and understanding by searching through the word of God and understanding the character of God.
Another powerful verse is Romans 8:16 The Spirit bears witness to our spirit that we are the children of God.
