We spend so much energy doing things to get approval from others and it consumes us, taking the joy out of life. When complimented, life is great, when not we wonder why!
Paul too – he found his identity in human achievements, yet in Philippians 3:4-10 (http://bit.ly/2QjtUS6), he says that was rubbish compared to the greatness of knowing Christ. A relationship with God gives us a secure identity in His love, so we don’t need to try to get self-worth, it comes from our relationship with Him.
We don’t have to do anything to value ourselves. He already Does.
