It is not nonsense. For those dead in Christ, they have yet to receive a glorified body which will occur at the Rapture of the Church. Believers who have died in Christ are said to be asleep in Jesus. I Thess. 4:13-16
Scripture says these words:
"absent from the body, present with the Lord."
When we die, we go to heaven immediately. It is NOT the same as when we are resurrected bodily and brought to heaven, but the orthodox position of the church has always been in opposition to the novel "sleep" theory that is only a recent introduction into the doctrine of some Christians.
