C.D. Cole offers his opinion on this topic:

This is one of the most difficult questions in theology. Since God made everything good in the original creation, how did sin get started?

God made everthing good, in that everything served his purpose ! Sin got started , because God decreed it for His purpose, else it would not have got started.

How was a good creation thrown into rebellion against its Creator?
this was part of Gods redemptive plan , and predetermined counsel.

By whom and how was sin originated?

answer: rev 4:11Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.

Sin was not created by God. God created everything good
Again wrong, all things are Good from Gods eternal purpose and Good pleasure, that is one of the comforts of scriptures like rom 8 : 28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.

even sin in the lives of true belivers today is good, in that it keeps us focused not on ourselves but on the merits of christ. We continually are dependent upon the blood of the lamb which cleanseth us from all unrighteousness..It causes us to look away from ourselves and utter those words as paul, I have no confidence in the flesh.

Sin is not eternal; it had a beginning.
Ah you don`t say ! Everything had a beginning but God. Sin had it's begininng in God's designated time, according to His good pleasure and sovereign will.

Sin was not the necessary result of finiteness.
That is not true. Man could not have remained in that state , nor the angels , because that would have made them immutable , which means they were not subject to change and Only the Thrice Holy God is mutable. Even the heavens are mutable and they never sinned. ps 102: 25, 2625Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands.

26They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed:

Now Holy writ does set forth one exception, and that is the elect angels who did not leave their first estate. They appear to be the only created beings that will remain unchanged. But they are elect, special grace, and I believe they are elected in Christ for that grand privilege !

Sin had its origin in a principle of negation, which means that it is not the result of any positive force
Oh so wrong <img src="/forum/images/graemlins/bash.gif" alt="" /> It was created by the positive force of God`s decree. True, God in his intrinsic Holy nature, committed no act of iniquity, but to relegate anything, or occurance , or activity, or action , or anyone as not to emante from His sovereign good pleasure and decree is Nigh blashemy. It is written that God hardened pharoah heart! ex 7:13 And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said.

ex 9: 12 And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses.

1 kgs 22; 23Now therefore, behold, the LORD hath put a lying spirit in the mouth of all these thy prophets, and the LORD hath spoken evil concerning thee.

To not see God`s positive decretive force behind mans sin is to ignore scripture truth...

So sin had its origin in the withholding of that grace necessary to sustain moral beings in a state of holiness. If God had not permitted sin there could have been no display of some of His most glorious attributes. Surely it is not too much to say that God permitted sin that He might overrule it "to the praise of the glory of His grace" (Eph 1:6).
Wow, God permitted sin only ?He decreed it,so He can demonstrate His overruling it and that for His glory. May he praised from all eternity..
