Matthew Poole and continuators on Titus 3:7

7 That being justified by his grace , we should be made heirs according to the hope of eternal life .

That we, through the free love of God, having the guilt of our sins removed, and the righteousness of Christ reckoned to us for righteousness,

should through Adoption be made Children, then heirs, heirs of God, and joint heirs with Christ, Rom. 8.17.

Some think that the words should be read thus, That we according to hope should be made Heirs of Eternal Life; because otherwise, the Text hath no object to relate to Heirs. But what should we be Heirs of, but the Kingdom mentioned Matth. 25.34? Though it be true, we are no more then Heirs according to hope, nor is any man otherwise an Heir of an Inheritance, as Heir stands distinguished from an owner or proprietor.
