Rev 7 reminds us that we who are marked with the "seal of God" as His servants "will be fully protected" and preserved. We will be among those in John's vision,"a vast crowd, too great to count, from every nation and tribe and people and language" marked with the seal of God, all shouting that our "salvation comes from our God on the throne and from the Lamb!". John was told in his vision that "they will never again be hungry or thirsty...for the Lamb who stands in front of the throne will be their Shepherd..and lead them to the springs of life-giving water".
