Romans 5:5

and hope putteth not to shame; because the love of God hath been shed abroad in our hearts through the Holy Spirit which was given unto us. [But the joy of the believer is not confined to this expectation of future good; he rejoices also in present evils, even in tribulation, because tribulation develops in him those elements of character which make him useful here, and prepare him for heaven hereafter; for tribulation teaches him that patience or steadfastness which endures without flinching, and this steadfastness wakens in him a sense of divine approval, and the thought that God approves adds to his hope that he shall obtain the blessings of the future world, and this hope is not so fickle as to disappoint or mock him, but gives him triumphant certainty, because the love which God has towards him fills his heart, being inwardly manifested to him by the Holy Spirit, who is given to all believers--at the time of their regeneration.]
