I’m certain Satan exists. God? Not so much.
*sigh*
God's law (aka Universal laws) are the rules to life IMHO. The 10 Commandments I believe was God's way simplify some Universal laws to everyone. That way there is no misunderstanding.
For instance, the law of attraction is we get back in life what we put out (aka Karma). That's why Jesus said forgive your enemies. It was not about kumbaya! It was to protect us from having what we put out boomerang right back to us. The only way to stop karma is through forgiveness. Forgiveness is more for you than for them.
There are other God laws like the law of Supply. This is why Capitalism beats out Communism every time. Communism goes against Universal law of Supply. Another law is the law gravity. I don't care how many times you step off the Empire State Building... you are going to fall! That is universal law. If you understand the law (rules to life), then life will begin to change for you. We manifest what we think about most. So if you want to change it think about what you want instead of what you do not want.
Science explains the how and Religion tells us why.
