15 Now that is the will of God which Christ both did and taught. Humility in conversation; steadfastness in faith; modesty in words; justice in deeds; mercifulness in works; discipline in morals; to be unable to do a wrong, and to be able to bear a wrong when done; to keep peace with the brethren; to love God with all one's heart; to love Him in that He is a Father; to fear Him in that He is God; to prefer nothing whatever to Christ, because He did not prefer anything to us; to adhere inseparably to His love; to stand by His cross bravely and faithfully; when there is any contest on behalf of His name and honour, to exhibit in discourse that constancy wherewith we make confession; in torture, that confidence wherewith we do battle; in death, that patience whereby we are crowned—this is to desire to be fellow-heirs with Christ; this is to do the commandment of God; this is to fulfil the will of the Father.
