'Alive' in the Bible

For now we are alive again, if you stand firm in the Lord.

For we tell you this by the word of the Lord, that we who are alive, who are left until the coming of the Lord, will surely not go ahead of those who have fallen asleep.

Then we who are alive, who are left, will be suddenly caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord.
