Psalm 26:2: Test me, O Lord, and try me; examine my heart and my mind.
Are you willing to allow God to judge you? Think about it before you answer; think about all the things you do, think and say, and then think about the question again!
It takes a brave soul to give over judgement to God and allow him to test you and to try you - he knows your weak points better than you do and you may not like the consequences.
Sometimes we do have to stop doing things for ourselves, stop doing things to make others think better of you and start doing things for God and to give him the glory.
Once we can let go of our self-importance and realise just how much we owe to God, life will start to change as you act on that!
