Part I: Sufficient Reason for the Existence of the Universe
Why is there “something” and not “nothing”? Why does our universe exist and why is it just the way it is?

Introduction
Children ask lots of questions. Each answer a child receives only prompts further questions. Seemingly never satisfied, the curious inquirers not only ask “what” and “how”, they also ask, “why?” Answers open doors to new rooms, inviting us to proceed for further discovery. As the questions probe deeper, many things become assumed fact without requiring further explanation. Yet the answers many of us received as children could not explain everything, so at some point we gave up asking. Answering one thing with another which itself also requires further explanation leads us nowhere.
Our final answer must be complete – able to explain itself without endlessly raising new questions. Such an answer must be something or somebody who is:
We will try to explain these attributes in detail. We will point out why only God can fulfill them and so be the sufficient reason for the existence of our universe. It might be difficult to start believing in God who is seemingly very abstract. Coming to believe in him goes hand in hand with getting to know him.
God is Unchangeable
The Jewish tradition contains the following legend about the childhood of their forefather Abraham:
(The little Abraham) saw the bright sun in the sky, and thought that it was God, who had created the heaven and the earth, and him, too. But in the evening the sun went down, and the moon rose in the sky, surrounded by myriads of stars. “This must be God,” Abraham decided. But the moon, too, disappeared, and the sun reappeared, and Abraham decided that there must be One who is the creator of the sun and the moon and the stars, and the whole world. (Midrash)
This legend illustrates that everything we see around us is changeable. Even the whole universe is constantly changing. A long time ago it was small and hot. Tomorrow it will not be the same as today.
Who directs the change? The universe itself? But it does not have its own will. Is there some law that controls the universe? But who defined it? …
When we say “God” we mean the one who has no beginning and no end and who does not change. His existence is completely independent of anything else.
“Every good gift and every perfect gift is from above, coming down from the Father of lights with whom there is no variation or shadow due to change.” (James 1:17)
God is Perfect
God is perfect in all his attributes. He is perfect love, perfect righteousness, and absolutely good. In every quality which we consider valuable, God’s goodness is complete. He gives us the deep and pure joy we truly need. There is no deficiency in him. Moses said about God:
“… his work is perfect, for all his ways are justice. A God of faithfulness and without iniquity, just and upright is he.” (Deuteronomy 32:4)
Our world is different. It is good but not perfect in the sense described above. In one Psalm we read:
To all perfection I see a limit, but your commands are boundless. (Psalm 119:96, NIVUK)
What is not absolutely perfect cannot be supreme either. Only a supreme being can be the final answer to all our questions.
God is Infinite
God is not limited by space and time because he created them. He is omnipresent (present everywhere simultaneously) and omniscient (knowing everything).
God is greater than our heart, and he knows everything. (1 John 3:20)
Not only does he know everything but he can also do anything he wants. Job said, “I know that you can do all things” (Job 42:2). This, however, does not mean that God will do something nonsensical, bad or contradictory to his nature. His unlimited attributes are united in goodness and integrity.
The universe is the sum of everything that exists around us. It is the sum of finite things and must itself also be finite. Even scientists say that the number of stars and the amount of energy in the universe, though beyond comprehension, is limited, and that our universe had a beginning.
Anything that is finite depends on something superior—something that determines its limits. Nothing but the omnipotent, one and only God can be completely independent and supreme.
Solomon said:
“Behold, heaven and the highest heaven cannot contain you.” (1 Kings 8:27).
God’s Existence is Independent
Existence is a gift—it is something we received. The example which we can identify with most easily is our own life. We are born once, and one day we will die. Our existence is dependent on many circumstances. We did not decide to live and we cannot simply decide whether or not we want to die. There are many conditions and external reasons for our existence. To answer the question why we exist, we must look for the answer outside of ourselves.
We find this to be true also concerning other things in this universe. We can directly observe the beginning and end of many things. In the case of other things, we may not observe their beginning and end, but at least we can observe their changeability. Everything that changes is not totally independent in its existence. The life of someone or something consists of periods which come and go and have a beginning and an end. We observe that not only we ourselves, but all things in this universe received their existence from outside. It is a gift. If somebody starts to see things from this perspective he will become deeply thankful for this gift of existence and will find its real purpose.
God’s being is very different. Because of his attributes described above, he does not depend on anything or anyone else. His own being is a sufficient reason for his existence. Because he is infinite, outside space and time, he does not need a creator. Only finite things need an origin. God is the one who gives existence and life. He created the universe out of nothing through his word.
“The God who made the world and everything in it, being Lord of heaven and earth, does not live in temples made by man, nor is he served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything.” (Acts 17:24–25)
“I am the Alpha and the Omega”, says the Lord God, “who is and who was and who is to come, the Almighty”. (Revelation 1:8)
Thus says the Lord, the King of Israel and his Redeemer, the Lord of hosts: “I am the first and I am the last; besides me there is no god.” (Isaiah 44:6)
Explaining Our Ability to Love
When the Bible says that “God is love” (1 John 4:8), it means that love belongs so deeply to his character that he cannot do anything against it. His love is not self-seeking. He does not need anything from us. He loves us for our sake.
God enables people to have a similar attitude. If people learn this from him then they become living proof of his work—proof that we are more than a product of blind chance struggling for survival.
Jesus called us to love our enemies.
“You have heard that it was said, ‘You shall love your neighbour and hate your enemy.’ But I say to you, Love your enemies and pray for those who persecute you, so that you may be children of your Father in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the righteous and on the unrighteous. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers and sisters, what more are you doing than others? Do not even the Gentiles do the same? Be perfect, therefore, as your heavenly Father is perfect.” (Matthew 5:43–48)
We can seek what is good even apart from our own personal benefit, such as when we seek the benefit of our family or friends. With God’s help we can love even our enemies. We find many examples of such people in the Bible. The best example is Jesus himself. He served selflessly his whole life. He did not profit from it, nor did he do it for human praise. During his suffering he persevered in humility and love towards all people. Who gave him the strength to do that?
If we turn to God, then God can completely transform our life. He enables us to live sincerely and love selflessly. Many people who met Jesus experienced such a change in their lives. He invites us to experience this change which we cannot achieve on our own.
Conclusion
God is a sufficient answer for the existence of our universe and the soul’s deepest questions. Because of our limits, we cannot understand everything about God. Yet with his help we can understand everything that is necessary for finding him. God lovingly reveals himself in many ways. He helps us to draw the right conclusions on the base of what we experience in the world and in our life.
God is not a theoretical reason for the existence of all things. Once we find him, we can enter into a relationship with him. Thus, the reality of God’s existence concerns not only our intellect but our whole being. We will never find peace and rest in a merely intellectual answer to our question about the reason for our existence. If we find God, we will know not only the reason for our existence but also its aim.
We do not know everything about God, but we know that he can exist independently of anything else. This is a big difference to the physical things. God can exist without the universe but our universe cannot exist without him.
