To keep our hearts pure, we must be clean on the inside and nurture chaste affections and desires. We need to keep our thoughts clean so as to be spiritually untainted in our devotion to Jehovah. (2 Cor. 4:2; 1 Tim. 1:5) How, though, do the pure in heart “see God” when, in fact, “no man can see [God] and live”? (Ex. 33:20) The Greek word rendered “see” can carry the sense of “to see with the mind, to perceive, know.” Those who see God with ‘the eyes of the heart’ are those who have really come to know him, appreciating his qualities. (Eph. 1:18) In addition to getting to know God’s qualities, true worshippers can “see God” by observing the way he acts in their behalf. (Job 42:5) They also focus ‘their eyes of the heart’ on the wonderful blessings that God holds out for those who strive to remain pure and to serve him loyally. w18.09 20 ¶13, 15-16
