Who is blind, but my servant? or deaf, as my messenger that I sent? who is blind as he that is perfect, and blind as the Lord's servant? Seeing many things, but thou observest not; opening the ears, but he heareth not. Isaiah 42:19, 20. OHC 334.1
What kind of blindness is this? It is a blindness that will not allow our eyes to contemplate evil. It will not allow our eyes to rest upon iniquity. It will not grasp the things of sight and lose eternity out of its reckoning.... We want to see aright, we want to see as God sees; for Satan is constantly trying to convert the things our eyes rest upon in order that we may see through his medium.... OHC 334.2
The servant of the living God sees to some purpose. The eyes are sanctified and the ears are sanctified, and those who will close their eyes and ears to evil will become changed. But if they will listen to those who will address them and try to lead their thoughts away from God and their eternal interests, then their whole senses are perverted by that which their eyes rest upon. Jesus says, “If ... thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness.” Matthew 6:22, 23. OHC 334.3
It makes every difference what we give our minds and souls to feed upon. We can let our minds dwell upon romance and castle-building, and what will it do for us? It will ruin us, soul and body.... We want to have that power that will enable us to close our eyes to scenes that are not elevating, that are not ennobling, that will not purify and refine us; and to keep our ears closed to everything that is forbidden in God's Word. He forbids us to imagine evil, to speak evil, and even to think evil.... OHC 334.4
I see in Jesus everything that is lovely, everything that is holy, everything that is uplifting and pure. Then why should I want to open my eyes wide to see everything that is disagreeable? By beholding we become changed. Let us look to Jesus and consider the loveliness of His character, and by beholding we shall become changed into the same likeness.38Manuscript 17, 1894. OHC 334.5
