"Create in me a clean heart, O God. Renew a loyal spirit within me" (Psalm 51:10).
David was not fake, in fact God himself calls him a man after His own heart. This is mind-blowing because he was not perfect. David was transparent about his flaws and mistakes. Throughout the Psalms he's often venting his heart to God through prayer, putting himself on the altar. Your best self, is your authentic self. Be exactly who you are – quirks and all! This will build your confidence and encourage your personality to shine through more and more.
