Here are 3 interesting questions raised at our last college retreat in my discussion group:
1) Does the absence of sin in heaven imply the absence of free will?
2) What do decisions look like at a molecular level; i.e. if all my decisions are ultimately reducible to chemical reactions at cell level, then where does my ability to make decisions reside?
3) If atoms from each living being are recycled when the living being dies, then what will our resurrected bodies be made of?
