I am in favor of Cremation. The soul goes on living, only the body dies. When the Lord returns we will be given new bodies.
The Bible tells us that when God's plan for the ages is complete and all evil is eliminated, we will be given new bodies -- bodies that will be like Christ's body after His resurrection. The Bible doesn't say exactly what they will look like, but our new bodies will no longer be subject to sickness or pain or death, and we will be able to serve God in ways we never could have imagined. The Bible says that on that final day "the trumpet will sound, the dead will be raised imperishable, and we will be changed" (1 Corinthians 15:52).
