The day of Jesus’ return is certain and coming, but—so far—it is not today. We find ourselves much like the Israelites long ago—waiting. Which begs the question: How then shall we wait?

Peter asks and answers this very question in his second letter. In love, he reminds his readers that, though the days seem long and weary in the waiting, God is not slow in keeping His promise. He assures them of the absolute reality of the appointed day when Jesus will return. And he then tells them exactly what kinds of lives they are to live in light of this coming day— lives of holiness, godliness, and hopeful expectation.

Peter’s exhortations are just as much for us today as they were for the believers he wrote to long ago. We too are living in the days of God’s patient mercy. We need to be reminded that really believing in and looking toward the reality of Jesus’ return changes the way we live. It reorients our hope and perspective. It creates a sense of urgency and sobriety, as well as giddy anticipation—just like a child who cannot wait for Christmas morning.
