These chapters describe the judgement of the whole of creation – it’s a fearful picture but woven through these chapters are reminders of God's desire to deliver people, His true and just character, and that judgement finally brings justice on all that is evil in our world. The call comes to respond by staying awake, and we do this through worship, through witness because the times are urgent, and by waiting in faith, knowing that as believers we are saved because of Jesus.
