Psalms 19:7 The law of the Lord is perfect, converting the soul: the testimony of the Lord is sure, making wise the simple. 8 The statutes of the Lord are right, rejoicing the heart: the commandment of the Lord is pure, enlightening the eyes.
[Patriarchs & Prophets pp 42] It was therefore necessary to demonstrate before the inhabitants of heaven, and of all the worlds, that God's government is just, His law perfect. Satan had made it appear that he himself was seeking to promote the good of the universe. The true character of the usurper and his real object must be understood by all. He must have time to manifest himself by his wicked works.
The discord which his own course had caused in heaven, Satan charged upon the government of God. All evil he declared to be the result of the divine administration. He claimed that it was his own object to improve upon the statutes of Jehovah. Therefore God permitted him to demonstrate the nature of his claims, to show the working out of his proposed changes in the divine law. His own work must condemn him. Satan had claimed from the first that he was not in rebellion. The whole universe must see the deceiver unmasked.
Even when he was cast out of heaven, Infinite Wisdom did not destroy Satan. Since only the service of love can be acceptable to God, the allegiance of His creatures must rest upon a conviction of His justice and benevolence. The inhabitants of heaven and of the worlds, being unprepared to comprehend the nature or consequences of sin, could not then have seen the justice of God in the destruction of Satan. Had he been immediately blotted out of existence, some would have served God from fear rather than from love.
Psalms 119:9 The fear of the Lord is clean, enduring for ever: the judgments of the Lord are true and righteous altogether. 10 More to be desired are they than gold, yea, than much fine gold: sweeter also than honey and the honeycomb. 11 Moreover by them is thy servant warned: and in keeping of them there is great reward.
May The Lord add His blessing to the study of His word. God bless!
