The Lord is the object of our faith. Our great desire must be for more light. God will responds to our cry for more light.
He revealed himself in Christ. He give his Word to quicken and enlighten our soul, and to illumine our pathway up to the gates of the land of glory “Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.” (Jh.8:12) David said “The Lord is my Light ”
“My” is a little word, but of great significance. Only a person can say My home, My wife, My child, faith is personal. It is one thing to say “God is light” another to say“God is my light”
It is one thing to cry “The Lord he is God” another “My Lord and my God.” (Jh.20:28)
This setting teachers us how we must become strong in order to meet danger, difficulties, temptation and the afflictions of life “There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.” (Rom.10:13)
We must have faith in the goodness of God.
Our faith is more than knowledge or feeling or obedience to the moral laws. It is a life. It not only implies trust, but love and service “Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:” (Heb.12:28)
There are times of difficulties and trials. David could look back in times of danger when he was in straits and fear, but God brought him help “David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and the LORD be with thee. (I.Sam.17:37)
Confidence comes from experience. Whom we have tried we trust “And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water.” (Mt.14:28)
The friend we have found faithful, we cleave to. The physician whose remedies we have proved good, we are confide in, so do we trust in Jesus.
In (v.13) David speak of the goodness of God. David has a firm assurance that God is good and he will manifest his goodness to him “be of good courage, and he shall strengthen thine heart:” (v.14) “God is good to all people, and his tender mercy is over all his works “and to give his life a ransom for many.” (Mk.10:45)
God will deliver and redeem us according to our need, we must believe that he is doing all that can be done for us, in seen and unseen ways beyond our power of interpretation “And there was a certain disciple at Damascus, named Ananias; and to him said the Lord in a vision, Ananias. And he said, Behold, I am here, Lord.” (Acts 9:10)
Waiting upon God means. Service to the Lord “The fool foldeth his hands together,” (Ecc.4:5)
Solomon also stated “Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.” (Ecc. 9:10) (Romans 12:1) clearly states “I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.” (Rom.12:1)
There is nothing so strengthening to our whole nature, nothing that so nerves us to meet danger and difficulties head on, as doing all that we know to be the will of God, doing all known duty “Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:” “While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.” “For they heard them speak with tongues, and magnify God,” (Ac.10:46)
An educating developing power, in obedience to duty, which nothing can take the place of it “Study to shew thyself approved unto God, a workman that needeth not to be ashamed,” (II.Tim.2:5
Waiting on God means, waiting for God, or, hope in him “Happy is he that hath the God of Jacob for his help, whose hope is in the LORD his God.” (Ps.146:5):
God has his own time and method of doing things.
We are saved by hope “If we hope for that we see not, then do we with patience wait for it,” (Rom.8:25)
We need to cultivat our courage. Our past successes is good for remember.
We need Moral courage as well as spiritual courage. David said to Saul “Thy servant slew both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God.” (1Sam.17:36)
Our personal experiences will empower us, and even same of our failures, when we see how they might have been avoided.
God is on our side, and He will help with the direct aid of his Spirit “If God be for us, who can be against us?” (Ro.8:31)
Things are possible to courageous minds which are impossible to weak, cowardly hearts “Let thine heart be strong.” “To him that believeth all things are possible” “With men this is impossible; but with God all things are possible.” (Mt.19:26)
