God doesn't care if you do not find the reason to believe in Him. In fact, atheism is within normal limits or expectations, given the magnificent task of recognizing Him! Failure to find God is one of the well-known side effects of creation possessing a knowledge of good and evil, or in other words, with a free will. When God created this world and gave human a free will, He knows that in many cases people will not find the real reasons to believe in Him and that is totally acceptable to him. He expects failures, well beforehand in this regard and those failures have their own roles to drive the world forwards, just like the Feminine that is driving the Masculine eternally.

Freedom of choice makes the faith/knowledge in God beautiful. If it were not a choice, rather only an automatic, uniform faith/knowledge written as if in a stone, then it will not be an exciting place to be in first place. It will be a boring, unimaginative, meaningless existence. Choice gives you the meaning. And freedom of choice is the ultimate meaning giver. Freedom of choice automatically engenders some degrees of atheism. So atheism is expected and it is not outside the norm of the divine plan. You are free to be an atheist and God understands it, totally. Atheism is just a minor and expected side effect of freedom of choice. God will not condemn for your atheism, just because you cannot come to the belief/knowledge in Him even after your sincere effort. Similarly, just because you believe in Him will not save you [as by Saviors of many theology] and will not give you immunity from punishment. Your actions define you and your reward or punishment. Atheism is not a problem or of any concern for God. The True God is too big to be dependent on the prayers and sacrifices from his subjects. But failure to recognize what you should care for is a problem because it is directly in your hand. You know what is good and what is bad. So there is no excuses for not doing good things to your fellow people and to this magnificent creation.

What is not acceptable to God is doing something bad, with full knowledge, which God cares for, i.e., the creation, including fellow people within this creation. It is also not acceptable to God to use His name for the personal gain of power, fame, money or control over others. It is not acceptable to God to create hurtful dogma and belief systems in the name of God. It is not acceptable to God to deceive and trick other people believing something untrue and hence causing great sufferings. These things are totally under your control, so you cannot use any excuses for your evildoings. If you hurt the creation and fellow people, you will NOT be excused by God, unless the victim excuses you. God does not simply care if you are an atheist or not, but he does care for his creation. Atheism is fine with God, but misusing your intellect and power to rip-off other people either morally, intellectually, physically, spiritually, or financially is not acceptable because it is totally in your direct reach. You have the choice and you know what is good and what is bad for people. If you really do not know then you will be excused but if you know but still do bad things then there is no escape. God will not condemn you just because of your atheism but He will not condone misuse of your power to choose. Be respectful to these principles and use your resources wisely.
