There is no proof of God beyond logic and faith. Those who wish to believe in God will use both faith and logic to do so. Conversely, those who are unable or unwilling to engage in specific logic and related mental effort—or who refuse to utilize any faith—will not believe in God.
God does exist. God is like an energy or principle. Within ethical monotheism, God is the source of all, the ultimate creator of Truth. God can make paradoxes real. While God could do evil, the nature of a perfectly loving God ensures that God would not.
Ideas and concepts like love and hate exist in a way similar to numbers. Numbers are an abstract idea, yet they have practical applications. In mental and spiritual space, we can add numbers conceptually. In reality, if there are two male ducks and two female ducks, then we have four ducks. Existence itself exists, and there must be a cause or reason for existence. This cause or reason may be beyond words and human comprehension, if one does not utilize both logic (mental effort) and faith.
To understand this cause or reason, we can use faith and abstract concepts to point to the ultimate Truth. Just as we can imagine the concept of infinity—though we can never fully count all the numbers within it—our human minds, constrained by time and space, struggle to grasp the infinite. Yet God, being infinite and beyond normal human perception, transcends these limitations. One can have faith that God can count all the numbers in infinity, doing so an infinite number of times with the ability to utilize infinite time.
The Catholic conceptualization of God holds that He is all-knowing, all-powerful, all-good, and all-present. Even to non-Catholics, this idea can make perfect logical sense if one is willing to use mental effort (logic) and faith. Believing in God is akin to understanding something that can only be fully known through experience. Unlike traveling to a foreign country—which requires a plane ticket and resources—believing in God and knowing His reality requires only faith, combined with mental effort and logic. Without a willingness to embrace faith and continuously apply logic and experience to strengthen it, one may not be able to fully perceive and understand that God exists.
