There's nothing God needs from you. There's nothing you can do for Him that He can't do better Himself. Your neighbor needs you though. The 4th commandment calls us to serve certain neighbors in certain ways. Start at home. Honor your father and mother.
Honor your father and mother that your days may be long in the land that the LORD your God is giving you. This doesn't mean you'll die younger if you talk back. It means there's more to life than winning the argument.
