Is cremation an acceptable alternative?

All my family knows that I want to be cremated, and that is stated in my Advanced Directive. I am trusting Yehovah that His words in Ecclesiastes 12:7, "Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it."  Yehovah created humanity from the dust of the earth and Adam's rib, so I am trusting that He can create my resurrected body to "house" or "tent" my spirit that returned to Him. I guess my "just desserts" would be to have to live forever in the mess I allowed of the body He first provided, but I am praying not. After all, He spoke the world into existence, who could put limits on His ability to re-create us in His image?
