But before proceeding to consider these words, it is absolutely necessary that we be on our guard against desiring this so needful a blessing from wrong motives. We must seek it for one supreme reason -- for the glory of God. If self is at the root of our motives at all, God will most surely block our way to Fullness of blessing. If we are thinking in our heart of hearts that it would be a good thing for us to get this blessing for our own happiness or satisfaction, or even that we might be more useful, or that in any way we might have the pre-eminence, our eye is not single, our whole body is not full of light (Matt. vi.22). There is therefore need for the refining fire to go through our heart. God must be Alpha and Omega in the matter. "For God's glory, and for God's glory alone" must be our watchword as we proceed with our search after the Fullness of the Spirit.
