According to our imperfect mode of knowledge and expression, the activities proper to God are to know and love Himself as He is in Himself, in His absolute unity and His ineffable Trinity. So the operations of the divine life as shared by us ought to tend proportionately, as to their worthy object, to the divine essence, not as a sterile abstraction, but as it is in itself, touching the one and triune God and reaching out to Him with those two powerful supernatural arms of knowledge and love which deigned to communicate to us.
For us to grasp to some extent the supernatural truths which far surpass our natural capacity, it is sufficient that we be illumined by the light of faith which presents them to us, however dimly and enigmatically, as incontestable facts. But worthily to appreciate these truths, we need to penetrate them, to know and feel them by a living faith which is accompanied by the gift of understanding and wisdom. This demands a high degree of purification. . ." pg. 120 "The Mystical Evolution" by Fr. John G. Arintero
" Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.
 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway." 1 Corinth. 9:24-27
