That is what I mean when I talk about people regarding the matter as if it were optional; and I like these words of Peter's because they show us a direct command: 'Be ye holy, for I am holy'. They fit in also with the other injunction: 'Come out from among them, and be ye separate, and touch not the unclean thing'. It is a grand and glorious privilege to have a clean heart; to have God Almighty coming and taking full possession of you; and to have His Holy Spirit day by day, filling your heart with love and keeping you in Divine fellowship. But I want you also to realize that it is a binding duty upon every follower of Jesus Christ to seek to become holy. I think it was John Wesley who said something to the effect that professing Christians who had not got the blessing of a clean heart, or were not earnestly seeking to be delivered from sin, could not consistently be regarded as Christians at all. I do not put it as strongly as that; but I do, from deep conviction, say this to you, that every Salvationist, and other persons who, in Meetings of this kind, are taught that the will of God is that they shall be delivered from all sin, that they shall live a life of purity and Holiness, that they shall walk in the enjoyment of a Full Salvation, and yet are not willing to follow the light, and do what they know God wants them to do, are probably heart-backsliders, and in a fair way to backslide altogether. I tell you, God has called you, not unto uncleanness, not to remain in a state of impurity, but to Holiness; and he that despiseth that calling despiseth not man, but God. Therefore, I beg of you not to imagine that, with clear light as to your duty, and the possibility of Full Salvation, you can either take it or leave it, and yet remain in the favour of God. Then these verses are very useful because they _set the standard for our personal spiritual condition_. Need I explain what I mean by this? Let your minds turn to weights and measures, and you will see my meaning exactly. If you went to a draper's shop, and asked for so many yards of material, you would not be satisfied by his guessing the quantity--you would want it measured by the yard-stick, the proper standard of measurement. So with weights. If you ask for so many pounds of sugar or potatoes, it would not be for the shopman to say to you, 'Will that do for you? Put another in? All right! Will that do?' You would say, 'Please weigh them properly according to standard'. Now it seems to me that in spiritual character we must have something by which we can measure and compare ourselves, and Peter gives us just such a standard when he says, 'As He which hath called you is holy, so be ye holy'. The standard is the character of God.
