Loving God

Browsing in From the Library of C.S. Lewis: Selections from Writers Who Influenced His Spiritual Journey I came across this:

At first, man loves himself for his own sake. That is the flesh, which can appreciate nothing beyond itself. Next, he perceives that he cannot exist by himself, and so begins by faith to seek after God, and to love Him as something necessary to his own welfare. That is the second degree, to love God, not for God's sake, but selfishly. But when he has learned to worship God and to seek Him aright, meditating on God, reading God's Word, praying and obeying His commandments, he comes gradually to know who God is, and finds Him altogether lovely. So, having tasted and seen how gracious the Lord is (Psalm 34:8), he advances to the third degree, when he loves God, not merely as his benefactor but as God. Surely this is the longest state for the one who is growing in God. As to the fourth degree, I know not whether it would be possible to make further progress in this life to that fourth degree and perfect condition wherein man loves himself solely for God's sake. Let any who have attained so far bear record; I confess it seems beyond my powers. Doubtless it will be reached when the good and faithful servant shall have entered into the joy of his Lord (Matthew 25:21), and been satisfied with the plenteousness of God's house (Psalm 36:8). For then in wondrous wise he will forget himself and as if delivered from self, he will grow wholly God's.

Bernard of Clairvaux (1090-1153)
