Finding the light is not a doctrine – It is about a Person.
“Then spake Jesus again unto them, saying, I am the light of the world: he that follows me shall not walk in darkness, but shall have the light of life.” John 8:12

If there is no light that you can see now; then look to where you last did see light, for even “while you are sitting in darkness; the Lord will be a light unto you. (Micah 7:8)
When temptations assail you, when care, perplexity, and darkness seem to surround your soul, look to the place where you last saw the light. Rest in Christ’s love and under His protecting care. When sin struggles for the mastery in the heart, when guilt oppresses the soul and burdens the conscience, when unbelief clouds the mind, remember that Christ’s grace is sufficient to subdue sin and banish the darkness. Entering into communion with the Savior, we enter the region of peace. MH 250 (1905).
The Healing Promises
“The Lord redeems the soul of His servants:
And none of them that trust in Him shall be desolate.”
Psalm 34:22.
“In the fear of the Lord is strong confidence:
And His children shall have a place of refuge.”
Proverbs 14:26.
“Zion said, Jehovah hath forsaken me, and
The Lord hath forgotten me.
Can a woman forget her sucking child,
That she should not have compassion on the son of her womb?
Yea, these may forget, yet will not I forget thee.
Behold, I have graven thee upon the palms of My hands.”
Isaiah 49:14-16, A.R.V.
“Fear thou not; for I am with thee:
Be not not dismayed; for I am thy God:
I will strengthen thee; yea, I will help thee;
Yea, I will uphold thee with the right hand of My
righteousness.” Isaiah 41:10.
“Ye that have been borne by Me from your birth,
That have been carried by Me from your earliest breath,
Even to your old age I am the same;
Even to hoar hairs I will carry you;
I have done it, and I will still bear you;
I will carry, and I will deliver you.”
Isaiah 46:3, 4, Noyes.
Nothing tends more to promote health of body and of soul than does a spirit of gratitude and praise. It is a positive duty to resist melancholy, discontented thoughts and feelings–as much a duty as it is to pray. If we are heaven-bound, how can we go as a band of mourners, groaning and complaining all along the way to our Father’s house? {MH 251.1}
Those professed Christians who are constantly complaining, and who seem to think cheerfulness and happiness a sin, have not genuine religion. Those who take a mournful pleasure in all that is melancholy in the natural world, who choose to look upon dead leaves rather than to gather the beautiful living flowers, who see no beauty in grand mountain heights and in valleys clothed with living green, who close their senses to the joyful voice which speaks to them in nature, and which is sweet and musical to the listening ear–these are not in Christ. They are gathering to themselves gloom and darkness, when they might have brightness, even the Sun of Righteousness arising in their hearts with healing in His beams. {MH 251.2}
Often your mind may be clouded because of pain. Then do not try to think. You know that Jesus loves you. He understands your weakness. You may do His will by simply resting in His arms. {MH 251.3}
It is a law of nature that our thoughts and feelings are encouraged and strengthened as we give them utterance.
While words express thoughts, it is also true that thoughts follow words. If we would give more expression to our faith, rejoice more in the blessings that we know we have,–the great mercy and love of God,–we should have more faith and greater joy.” {MH 251.4}
In reviewing our past history, having traveled over every step of advance to our present standing, I can say, Praise God! As I see what the Lord has wrought, I am filled with astonishment, and with confidence in Christ as leader. We have nothing to fear for the future, except as we shall forget the way the Lord has led us, and His teaching in our past history. {RH, October 12, 1905 par. 22}
Its not wrong to fall down, or to make a mistake, or to utterly fail, or to suffer great tragedy. None of these things declare in any way who or what you are. It all just means you are still in the race.
But as for me, I watch in hope for the LORD, I wait for God my Savior; my God will hear me. Do not gloat over me, my enemy! Though I have fallen, I will rise. Though I sit in darkness, the LORD will be my light. (Micah 7:7-8)
When darkness assails you, when care, perplexity, and doubt seem to surround your soul, look to where you last saw the light. Rest totally in God’s love, and in His protecting care. When the bleakness of the storm struggles for mastery in the heart, when guilt oppresses the soul, or doubts burden the conscience, when unbelief clouds the mind, remember, God’s grace is sufficient to subdue it all and to guide you into the region of true peace, where God’s grace will bring you patience, trustfulness, and melt away the restless waves of weakness. He will warm your heart with His own sweet Spirit; He will revive your soul.
If you are struggling right now, may you remember that tomorrow is another day. And that there is always hope. May you remember what a gift you are to the world, and that you are perfect just the way you are. May you remember that even when you feel lonely, you are never truly alone; for as the Bible says you are surrounded by angels who love you beyond measure.
