Ephesians 1:14, 18

The Spirit is the guarantee [the first installment, the pledge, a foretaste] of our inheritance until the redemption of God’s own [purchased] possession [His believers], to the praise of His glory.

And [I pray] that the eyes of your heart [the very center and core of your being] may be enlightened [flooded with light by the Holy Spirit], so that you will know and cherish the hope [the divine guarantee, the confident expectation] to which He has called you, the riches of His glorious inheritance in the saints (God’s people)
