>morality comes from "god"
Morals long preceded organized religions by tens of thousands of years.
All your purpose and morality comes from within you, if you're not an NPC who sold off these faculties to a bunch of Middle-Eastern merchants.
All human morals are established by men, including the ones in your bible. The ones I follow just don't have the Jewish fairy tale aspect to it.
Even animals have certain morals that allow them to survive and cooperate in a group, i.e. helping each other when in danger and sharing food.
If you claim that morality (i.e. objectively good behavior) comes from your "god", then here's how you prove it:
1. Prove your "god" exists
2. Prove your "god" is benevolent enough to follow his moral code, and
3. Prove your "god" is the author of said moral code, not the men who actually wrote them.
Don't worry, you'll never get past step 1.
