I have done (or not done) said (or not said) things with a motivation that misrepresented God.
Why you do something is more important than what you do. If you are doing something out of the wrong motivation you are misrepresenting God and in so doing hurting yourself and others. God has only ever wanted you for no other reason other than there is nothing he wants more than you. Not out of obligation or a sense of duty, but freely because He actually wants you.
I believe if you are enabled to know how much he wants you, you will be more able to be motivated out of no other motivation than wanting nothing more than you want him, thereby representing Him to a greater extent.
Psalm 36:7 How priceless is your unfailing love, O God! People take refuge in the shadow of your wings.
It is far better to be unknown, broke, and physically sick yet motivated by wanting God, than be famous, rich, and healthy, yet misrepresent God in your motivations. I believe one way to help you is to help you allow God to change your motivation. One way this can occur I believe is to help you allow yourself to know God better and to turn back (repent) from wanting to misrepresent God in your heart. God wants to help you wanting nothing more than Him to the same extent God wants nothing more than you.
