There is only one answer, free will. You might not like it but God created us to have the power to reject or ignore God. You have been designed to co-create with God, communicate with God, hear from God and interact with God in the every processes of life. You choose. You can initiate interaction with God and you can deny God access to your inner man, that part of you that corresponds with God.
It is not complicated, nor is it cumbersome and it is immediately available. Here's the part that many people don't like. The creator designed you to operate in full self-power mode without access to or integration with or communication with God. In every way you can be free from any influence of God. That's the idea behind free will. Free from or free to engage with. You choose.
Now you might be thinking that if left to our own devices we would all choose not to communicate with God, because if God does not initiate the conversation, communication, connection then it must not be very important. You are absolutely right. The problem with that theory is that God implanted in every human His image. This image is always there whether you initiate any desire to meet, see, understand or communicate with God. This image is in the inner man.
Your inner man was made in the image and likeness of God. . The mind will grow old and become dim, the body grows old and comes to an end, the soul continues on forever and the spirit continues on forever, but the spirit is activated, made alive by accepting the gift of God and that is done through the inner man. There is no spiritual connection to God without being activated by the inner man. There is body, mind, soul and spirit. The inner man is the mind of the spirit and soul. Everything spiritual is initiated via the inner man. If you are a woman, the inner woman.
