The obedience of faith

   "The path of obedience in the pursuit of holiness is often contrary to human reason.  If we do not have conviction in the necessity of obeying the revealed will of God as well as confidence in the promises of God, we will never persevere in this difficult pursuit.  We must have conviction that it is God's will that we seek holiness—regardless of how arduous and painful the seeking may be.  And we must be confident that the pursuit of holiness results in God's approval and blessing, even when circumstances make it appear otherwise."
