I pray that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints,Ephesians 1:18(NASB)
All believers have been called by grace, out of darkness into His glorious light. We have been called by grace, to glory. We have been called, chosen, justified and glorified for we are saved by grace through faith in Christ and are become his chosen people, a royal priesthood, a holy nation. We are God's very special possession - His glorious inheritance.
Sometimes familiarly with the glorious superlatives of our heavenly calling, and the eternal hope of glory that is set before us, causes our eyes to become dimmed and our hearts to become complacent. Sometimes the passing enticements of this world seek to blind our eyes to the riches of the glorious inheritance that we have in Christ Jesus our Lord.
It was Paul who rejoiced in the confident hope that we have in Christ Jesus and he longed that others too would come to a real understanding of the incomparable riches of His grace, which is expressed in his kindness towards us in Christ Jesus and so Paul prays that the eyes of our heart may be enlightened in order that we may know the hope to which God has called us - the riches of His glorious inheritance in US - His holy, called-out people.
Heavenly Father, I pray that the hearts of all Your children may be flooded with the marvellous light of the gospel of grace and glory that is given to all who trust in Jesus as Saviour - Help us all to understand the confident hope we have in Christ Jesus our Lord, Whom to know is life eternal, in Whose name I pray, AMEN.
