The key to Paul's persistence in ministry was his focus on the things that could not be seen. Part of that unseen world, something that was so supportive to Paul, was his certainty of heaven, or eternal life with Jesus. In this passage we'll hear Paul's testimony about what lay ahead for him, and we'll hear him tell us how that expectation impacted how he lived. There is instruction for us, too, as we learn more about what lies ahead for us, and how that can change how we live today.
