Holy Life is a manifestation of our love for God. We do this according to Romans 12:1 not because we need to feel righteous or win favour points in heaven. This is an obligation that shows obedience to Him. Life is promised to the obedient, it takes great faith to deny oneself and follow God and His precepts. As pilgrims journeying through, we must always say with 2 Cor 5:15... Not I but Christ
