In view of the possibility of a nuclear disaster in Japan due to the recent earthquake, it seems that God sets limits to how far we should explore on our own. We discovered nuclear fission so we're able to build reactors as well as the bomb and look how much trouble it has gotten us into. Maybe there are things we should not touch, like the forbidden fruit in the garden of Eden. I see cloning as one of these areas. The Lord wants us to seek his will, listen to him and follow him, but mankind has taken off in the opposite direction, forgetting that we reap what we sow.
Looking at our earth, a relatively puny, round body in the universe. It's covered mostly with water, so our continents are basically islands amidst the vast oceans. We are like creatures marooned on these islands for a limited period of time ~ how then can we call these lands our home? To just plan for a good education, a good job, and financial security for ourselves in the world but nothing beyond is sheer folly.
