What should we beware of when we seek to obey God's commands?

We should not fall into the trap where we outwardly obey the commands of God but yet in our hearts, its actually willful disobedience.

Deut 5:29 "Oh, that their hearts would be inclined to fear me and keep all my commands always, so that it might go well with them and their children forever."

With outward actions, we obey. More importantly, we obey in reverent fear to God in our hearts. We do this because He is God. And a added bonus is, He blesses us when we do so.
