The answer in today’s text is very simply, the grace of God. Our hope is rooted in the grace of God. It is based on the grace of God. If God were not a gracious God, we would have no hope. We could cross our fingers. We could have strong desires and wishes. We could even perhaps decide, by sheer dint of will-power, to be positive thinkers and thus make the best of our brief and uncertain lives. But there could be no talk of moral certainty about good things in the future. There could be no confident expectation that all things will work out in a wonderfully happy way for us.
The foundation of that confidence—that biblical hope—is the grace of God. Let’s get the text of God’s Word before us. 2 Thessalonians 2:16–17,
Now may our Lord Jesus Christ himself, and God our Father, who loved us and gave us eternal comfort and good hope through grace, comfort your hearts and establish them in every good work and word.
The phrase that we will focus on is the phrase, “good hope through grace.” The hope we have is a good hope. And it comes to us “through grace” or “by grace.” So when someone asks you a reason for the hope that is in you, one basic answer you can give is that you have tasted the grace of God. You have gotten your good hope through his grace.
