Admittedly there is no direct command regarding burial or prohibition of cremation. While the act of cremation, as such, is not a sin or an intrinsic evil like murder, burial is the general pattern set down in Scripture. Its continued practice is a reasonable inference drawn from biblical truths. Thus we believe the evidence supports the conclusion that Christians, if at all possible, should practice burial. It is more symbolically appropriate to do so.
Christian burial follows the example of Christ. Jesus interment is described in great detail and was clearly a burial (Matt. 27:5761; John 19:3842). The fact that Jesus was resurrected three days later (according to Jewish reckoning), in the same body in which He died, gives assurance to the believer (John 20:130; Phil. 3:2021). Burial not only shows respect for the body but it also symbolically anticipates its future in the resurrection. Cremation, on the contrary, is more of a picture that death is the end of everything. Just as Christian baptism is symbolized by death and resurrection (Rom. 6:1ff.), so proper Christian burial can be part of the same picture.
Paul used Jesus burial as part of the Gospel message in 1 Corinthians 15. Burial is an essential part of the gospel since Paul defined the gospel as involving death, burial, and resurrection appearances. Burial is the seal of death and resurrection is proof that death is not final.
