Q2. (1:13-15) Why do people blame God for evil? Does God tempt us with evil? Does he tempt sinful people with evil? Why does he allow people to sin? Why does he allow evil to exist at all?
It is easy to blame God for any of our failures or shortcomings in life but that seems to be more of a sign of immaturity or ignorance from not having a continuing relationship with God. When God created this world, He looked at all He had done and called it VERY GOOD. It was complete and perfect without evil, but through Adam, Eve, and Satan, evil and sin was introduced into this perfect world and to this day we are suffering the consequence. Like a disobedient child trying not to be punished, blame is put on anything, or anyone but themself.
God cannot tempt anyone and He cannot be tempted.
Through freewill he allows us to make choices in our life and like a father, urges us on to make the right choice but the choice is still ours in the end. I think God allows us to sin so that we can realize the difference between right and wrong and aim towards right in order to recieve the crown of life (James 1:12). If we are not continually making decisions, right or wrong, how do we expect to grow from our sin?
In kind of the same way as the above, evil exists so we can grow and overcome evil and so the love of God can be seen.
