They think they are safe, they have a false sense of security. They have no idea that judgment is at hand. Christians live in the light. We may not know when judgment is coming, but we do know that it is coming. So we do not fear this day, for we know that God is a God of grace in Christ.
Christians live now and in the future with faith, hope, and love.
One might say this is the equipment worn for watching for the coming of Christ, a kind of guard duty, the kind of things the Christian does awaiting the coming of Christ. God in Christ has provided for all we need - freedom for a sinful past, our present needs met, our future assured. Give us confidence in you. For just as you ahve been there in the past, are with us now, we know you will be with us always. So we will fear nothing, but seek to serve you in the best ways we know how each day until that Day.
