It will happen in an instant, in a split second at the sound of the last trumpet. Indeed, that trumpet will sound, and then the dead will come back to life. They will be changed so that they can live forever.
This is what you asked the Lord your God to give you on the day of the assembly at Mount Horeb. You said, “We never want to hear the voice of the Lord our God or see this raging fire again. If we do, we’ll die!”
The Lord will come from heaven with a command, with the voice of the archangel, and with the trumpet ⌞call⌟ of God. First, the dead who believed in Christ will come back to life.
Be careful that you do not refuse to listen when God speaks. Your ancestors didn’t escape when they refused to listen to God, who warned them on earth. We certainly won’t escape if we turn away from God, who warns us from heaven.
