Listen, I tell you a mystery: We will not all sleep, but we will all be changed-- in a flash, in the twinkling of an eye, at the last trumpet. For the trupet will sound, the dead will be raised imperishable, and we will be changed. For the perishable must clothe itself with the imperishable, and the mortal with immortality.....
THIS SONG is one of my favorites in regards to Christ's return. It goes right along with this scripture. (I want this sung at my funeral one day by the way.)
But let's not forget about verse 58 below....it's our responsibility!
Therefore my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
1 Corintians 15: 51-53, 58
