Even after being born again I continued to wonder - what is righteousness and sin? Was I always supposed to do everything right and perfectly because I am under HIS radar? I knew HE loved me but did HIS pleasure in me fluctuate according to my performance?  

For if Righteousness could be gained through the law then Christ died for nothing (Galatians 2:21). Righteousness from God comes through faith in Jesus Christ to all who believe (Romans 3:21-22).
