"God can use our wrong motives for good purposes."

This phrase has been resounding with me the past couple of weeks.

I want to leave so badly and in a bid to do so, have been giving myself the wrong "justification" for leaving.

But you know they say, God can use our wrong motives for good purposes. In this vein, will my wrong motivations ultimately be for His purposes? And if so, can I justify myself for my wrong motives?
