through whom we have gained access by faith into this grace in which we now stand. And we boast in the hope of the glory of God. Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us.
