The rapture is the event when God will resurrect all believers in Christ and take them to Heaven. This includes those who are living and those who have died. God will give them glorified bodies at that time. At the rapture, when we rise the Lord will meet us in the air (1 Thessalonians 4:17). The Lord will come like a thief in the night. (1 Thessalonians 5:2). It will be in secret. Only His children will hear the trumpet sound that Jesus has come. No one knows the day or time so we must all be ready.
