"The motive for loving God is God Himself. I spoke truly, for He is as well the efficient cause as the final object of our love. He gives the occasion for love, He creates the affection, He brings the desire to good effect. He is such that love to Him is a natural due; and so hope in Him is natural, since our present love would be vain did we not hope to love Him perfectly some day. Our love is prepared and rewarded by His. He loves us first, out of His great tenderness; then we are bound to repay Him with love; and we are permitted to cherish exultant hopes in Him. 'He is rich unto all that call upon Him' (Rom. 10.12), yet He has no gift for them better than Himself. He gives Himself as prize and reward: He is the refreshment of holy soul, the ransom of those in captivity. 'The Lord is good unto them that wait for Him' (Lam. 3.25). What will He be then to those who gain His presence? But here is a paradox, that no one can seek the Lord who has not already found Him. It is Thy will, O God, to be found that Thou mayest be sought, to be sought that Thou mayest the more truly be found."
(Bernard of Clairvaux, On Loving God)
