Some people do not believe in the resurrection of the body, to them, everything ends with dust and a grave. Others are afraid of the resurrection and to escape it they incinerate their bodies forgetting that their ashes same as dust will form back into a body through God. But those that have placed their trust in God and believe in his word know that the body placed in the grave is like a seed that will one day come out resurrected. When the Lord Jesus returns the believers that have died will resurrect and in an instant will be taken to heaven with the believers that still live at that time.
