Sin is anything outside the will of God. God never does anything outside His will. Therefore, He has no need for forgiveness.

You attempting to ascribe your erroneous view of things does not make God a sinner.

God allows free will. Thus, He allowed Satan to do things to Job. And, Job grew closer to God because Job was a righteous man.

He never coveted the wife of Joseph. It is only a perversion of the story that causes people to put sex into Mary's conception. Reasonable people understand that a virgin birth could not occur if sex had. God caused the formation of Jesus in her womb supernaturally (because God is supernatural).

As th Bible explains, the Sabbath was made for man. It was the Pharisees (also not always a reasonable group) that raised the complete absence of work on the Sabbath. The priests had always worked on the Sabbath. It was also the Pharisees that made Saturday the Sabbath. If you searched God's word (instead of man's ideas), you will find no such mention.

Why is it that sinful man seems to want to judge a holy God? Feeling guilty?
