The Apostle seems to connect hope more immediately with the cleansing, and holiness with the fear of God, but probably both hope and fear are in his mind as the double foundation on which both purity and consecration are to rest, or the double emotion which is to produce them both. These promises refer directly to the immediately preceding words, I will be a Father unto you and ye shall be My sons and daughters,' in which all the blessings which God can give or men can receive are fused together in one lustrous and all-comprehensive whole. So all the great truths of the Gospel and all the blessed emotions of sonship which can spring up in a human heart are intended to find their practical result in holy and pure living. For this end God has spoken to us out of the thick darkness; for this end Christ has come into our darkness; for this end He has lived; for this end He died; for this end He rose again; for this end He sends His Spirit and administers the providence of the world. The purpose of all the Divine activity as regards us men is not merely to make us happy, but to make us happy in order that we may be good. He whom what he calls his religion has only saved from the wrath of God and the fear of hell has not learned the alphabet of religion. Unless God's promises evoke men's goodness it will be of little avail that they seem to quicken their hope. Joyful confidence in our sonship is only warranted in the measure in which we are like our Father. Hope often deludes and makes men dreamy and unpractical. It generally paints pictures far lovelier than the realities, and without any of their shadows; it is too often the stimulus and ally of ignoble lives, and seldom stirs to heroism or endurance, but its many defects are not due to itself but to its false choice of objects on which to fix. The hope which is lifted from trailing along the earth and twining round creatures and which rises to grasp these promises ought to be, and in the measure of its reality is the ally of all patient endurance and noble self-sacrifice. Its vision of coming good is all directed to the coming Christ, and every man that hath this hope in Him, purifieth himself even as He is pure.'
In Paul's experience there was no contrariety between hope set on Jesus and fear directed towards God. It is in the fear of God that holiness is to be perfected There is a fear which has no torment. Yet more, there is no love in sons or daughters without fear. The reverential awe with which God's children draw near to God has in it nothing slavish and no terror. Their love is not only joyful but lowly. The worshipping gaze upon His Divine majesty, the reverential and adoring contemplation of His ineffable holiness, and the poignant consciousness, after all effort, of the distance between us and Him will bow the hearts that love Him most in lowliest prostration before Him. These two, hope and fear, confidence and awe, are like the poles on which the whole round world turns and are united here in one result. They who set their hope in God' must not forget the works of God but keep His commandments'; they who call Him Father,' who without respect of persons judgeth' must pass the time of their sojourning here in fear,' and their hopes and their fears must drive the wheels of life, purify them from all filthiness and perfect them in all holiness.
