Hi Jos
Christians argue that God is the standard and model for moral perfection and they also argue that God can't do evil and always does the right thing because there is no corruption or character flaw in Him.
Where God resides in highest heaven and the heavenly host there is no evil there is no harm and no imperfection.
Why would God need to do evil? I personally do not see that a Christian would argue the above.
As for his character the bible itself suggests God has prefect knowledge and perfect judgment so he can judge rightly all things. The only problem with humans is seeing God as human.
You see Gods character has no flaws but God isn't a character he is a Spirit and he is perfect in knowledge of right and wrong. We cannot escape the fact that right and wrong or Good and Evil exist. If someone walked into your home with a gun and was about to kill your family would you kill them first if you had a gun?
Unlike us, God tells the end from the beginning. He sees all things and a thousand years is like a day to him. How do you judge the person called God, the perfect person by human standards?
I would suggest reading up on God and his character and ask yourself where would we be if he had not been there to ensure humanity survived.
So according to your worldview, assuming your a Christian, yes there is such a thing as moral perfection ie. God and He always does the right thing. Don't you affirm that God's nature is the perfect, objective standard for morality and that it doesn't matter whether humans agree or disagree on morality since God's perfect standard is what matters?
Belief in God is not about the world or the moral standards as these are nothing to do with the relationship a person has with God.The World is corrupt and has been since the fall but humans like yourself can always choose what they want to do. WORLDVIEW... how would you summarise this?
Wiki suggests
A world view or worldview is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge and point of view. A world viewcan include natural philosophy; fundamental, existential, and normative postulates; or themes, values, emotions, and ethics.
believers are a new creation no longer born of the things of this world. They live for God in this world and they do the good things and do not harm others.
So it is a heavenly view not a world view a believer would have.
