The problem of sin

Here is how I see this:

[James K] How do you address the problem of sin?

This is a variation of the problem of evil. Evil is by its nature a negation of some kind of good. There can be no evil without there being good to negate. Absolute good though has no need of any evil. Relative good may require an evil or negation of another’s good. (A spider eats a fly.) (To lie to those who would do evil to protect the good.)

Now the fall of man is covered in the book of Genesis, and the sinful nature of man is caused by man obtaining God’s knowledge of good and evil. (see Genesis 3:22.) So knowledge of evil can lead man to do an evil or have evil thoughts, Where as the knowledge of good can cause man to be self condemned for evil or thoughts of evil.

God who is infinitely good cannot be affected by evil. Whereas finite good man is rendered sinful by the knowledge of evil.

infinite good + any evil = infinite good. (infinite good is unaffected by any evil.)

finite good + any evil = evil. (no longer good.)

Did God ordain it?

God indeed ordained what sin was. But remember God is the infinite good in this. We think in terms of being finite and ordaining it, which cannot apply to infinite good in any way.

Did God want it?

What God wanted is in the context of His infinite goodness. So wanting there to be sin defined, from our finite view cannot apply here.

Did God give man an the chance to not sin?

Of course. (Genesis 2:17.)
