Ezekiel is brought before the Valley of Dry Bones. And the question is, "Can these bones live?" In other words, can life come from death? The answer: God can. And by His Word the dry bones came back to life. This is just like we, who are dead in our trespasses and sins, can be brought from death to life. This happens through Christ's death and resurrection. This happens through the means of grace, God's Word, and His Sacraments. And this isn't just about our earthly life, this is also about our eternal life.
