How did God decide what is right and wrong?
Here's the answer:
God is perfect and knows what is best.
When someone makes a new game, they get to make the rules to it. When God made the world, He got to make the rules for how we are to live. The Bible teaches us what God says is right and wrong (2 Timothy 3:16-17).
Sometimes, we would like to make our own rules. We don’t like to clean our room or eat our vegetables, but our parents know what is important. God is way smarter than our parents! He knows exactly what is best for our lives.
Just like our parents, God tells us what is right and wrong because He loves us. He loved us so much that He sent Jesus to make a way for us to know God (John 3:16). When we believe in Him, He gives us strength to do what is right. We can trust Him because He loves us.
"The rules of the LORD are right. They give joy to our hearts..." (Psalm 19:8).
"God’s way is perfect. The LORD’s word doesn’t have any flaws. He protects like a shield all who go to him for safety" (2 Samuel 22:31).
