For this we say to you by a word from the Lord, that we, the living ones remaining unto the coming of the Lord will never precede the ones who are sleeping (1 Thessalonians 4:15).
When a grace believer passes away, he does not lose his part in joining the rapture. The ‘rapture’ is the term used to describe the snatching away of the Church from the earth by Christ when He returns in the air just prior to the beginning of the Tribulation period.
Since we believe that Jesus died and rose again, God will bring with Him those who sleep.
