Just as I said earlier, you need a deeper understanding of religion to understand the above........and many other things. When we accept that Islam is Gods religion, amongst others like Christianity and Judaism, we submit ourselves to every word and every rule. Then we acknowledge that this life and everything attached to it are also gifts from God. When God orders us to execute murderers and rapists, He is merely ordering His subjects to do His bidding on His subjects. This life is His gift and He has total authority over it, He decides what punishments we must face and what rewards we reap in this life and the afterlife.
