Romans 5:5

And hope maketh not ashamed
As a vain hope does, things not answering to expectation, it deceives, and is lost; but the grace of hope is of such a nature, as that it never fails deceives, or disappoints: it neither makes ashamed, nor have persons that have any reason to be ashamed of it; neither of the grace itself, which is a good one; nor of the ground and foundation of it, the person and righteousness of Christ; nor of the object of it, eternal glory:

because the love of God is shed abroad in our hearts by the Holy
Ghost, which is given unto us.
By "the love of God" is meant, not that love by which we love God, for hope does not depend upon, nor is it supported by our love and obedience to God; but the love of God to us, of which some instances are given in the following verses: us is said "to be shed abroad in our hearts"; which denotes the plenty and abundance of it, and the full and comfortable sensation which believers have of it: "by the Holy Spirit": who leads into, and makes application of it: "and is given to us": for that purpose, as the applier of all grace, the Comforter, and the earnest of heaven. Now the love which the Spirit sheds abroad in the heart, is the source and spring, both of justification itself, which is owing to the free grace of God, and of all the effects of it, as peace with God, access to the throne of grace, rejoicing in hope of the glory of God, the usefulness of afflictions, and the stability of hope, and is here alleged as the reason of all.
