Because God is in control, and because he wants freedom for people, and because He observes everything, the only way for us to keep our freedom is to freely come to know God, and to have a free and right relationship with Him. There are 3 ways that God introduces Himself to us, so that we hopefully get into a right relationship with Him:
God gave people freedom - this is the greatest gift that can be given. Therefore, even when we are not on the side of God, but on the side of the devil (when we are not doing good deeds, but doing bad deeds), then this is our choice, because God gave us the freedom to choose. This is necessary in order to develop your spiritual side, possibly, it will take several lives (reincarnation). However, any person can develop his spirituality in one life, if he chooses it and will strive for God every day.
Yes, God is everywhere, but God does not want our endless deaths and rebirths. It is our choice when we act badly (no matter what).
But God is always open to us if we choose his side. It is never too late to start living high ideals such as sincerity, friendship, true all-encompassing love, conscience, etc.
God is one for all people, no matter what you call him (depending on religion or culture). Spiritual knowledge is in all religions and different spiritual movements. It is important to understand them correctly.
We can turn to God only to guide us on the spiritual path. If we ask for something materially (health of the physical body, well-being of the family, etc.), then we ask for it not from God, but from the devil, because the nature of God (and our soul) is spiritual and immortal. Everything material in this world is mortal. Of course, we should monitor our health, make money out of necessity, but our main goal is to achieve immortality, i.e. connect with the spiritual.
Or in other words - those who do not accept God, but accept the devil, will destroy themselves.
All people have essentially destroyed themselves in this life, through death. Those who are blatantly and formally evil, bring an early death on themselves... partially because the universe is directed towards good by God, and partially because God is protecting those who are not so blatantly and formally evil.
However, the timing is up to God. At times He lets evil people last a long time, while believers are taken home early in life.
