A Short Study of Isaiah 12:2
“And in that day thou shalt say, O LORD, I will praise thee: though thou wast angry with me, thine anger is turned away, and thou comfortedst me. Behold, God is my salvation; I will trust, and not be afraid: for the LORD JEHOVAH is my strength and my song; he also is become my salvation. Therefore with joy shall ye draw water out of the wells of salvation.”
A believer finds great comfort in pointing to the One Who has met all requirements, and satisfied all demands of the law of God for His people.
While other men may speak of their baptisms, professions of faith, or any other religious activity which they feel justifies them before God, a redeemed sinner most joyfully points toward Christ for the hope and cause of his salvation.
The believer has been given a trusting faith by the Holy Spirit. He trusts God, and, at the same time, realizes that the faith by which he believes is not of himself but of God (lest he should foolishly boast of having done something himself to merit salvation).
This awareness of his spiritual weakness causes such an enlightened sinner to constantly cast himself upon the mercies of Almighty God. He knows that if God ever depended on him to maintain his salvation (even for a moment), his spiritual situation would be hopeless.
This blessed fact (that God will not leave a man to himself) dispels all fear of eternal damnation.
A believer is not afraid [and need not be] that possibly there are “skeletons in the closet” which will be brought up at the day of judgment.
Though God’s people know that they are prone to wander, they rest without fear in the One who is able to keep them unto the day of salvation.
