Psalm 106:3: Blessed are those who observe what is right and always do what is just.
Many people who I have spoken to about the bible look at their bibles as being a guidebook which encourages them to do what is right - why?
Because of the many references to things like this in the bible; both New and Old Testaments carry many encouragements to do what is righteous, if not for others sake, then for your own sake!
God really does like it when people 'listen' to his word and follow his word. He is like a proud parent when their child does what is right!
If you can receive good gifts from your parents when you do things right, then how much more can God give you when you follow his will in your life!
