How do I know that God exists?

Perhaps this is the most fundamental question that you could ever ask. How do you know that God is really there? Is there clear evidence for believing in his existence? Well, although there are many arguments that we could use, we are going to home in on four.

a. The Existence of the Universe. Just by observing life in general we notice that some things cause other things to be. For example the words that you are reading right now are here because someone sat down in front of a computer and typed them! We call this 'cause and effect'. The writer is the cause and the words are the effect. But this principle, which can be seen multiplied countless times throughout our world, leads us to ask 'what was the first cause?' Or to put it another way 'what brought the universe into being?'

Many scientists answer this question by arguing that the universe is the result of the 'Big Bang', but even if we accepted this questionable theory just for the sake of argument, yet it doesn't actually answer our question, because we are still left wondering how matter came into existence and what caused the 'Big Bang' in the first place.

We are left with only two possibilities. The first is that the universe has always existed, which few would argue in support of, and the other is God. As an Uncaused Being he must have brought the universe into being and set everything else in motion just as the Bible tells us.

b. Design within the Universe. If you consider our world again for a moment, you cannot help being struck by the beauty and intricacy of everything. Wherever you look there is order, harmony and purpose, but where do these things come from? Some would answer by saying that chance has produced this intricate world, through an evolutionary process. However, an increasing number of scientists are arguing that our world displays clear signs of intelligent design and they point to what is called 'irreducible complexity'.

To illustrate this complex idea, think of a mousetrap. A mousetrap has several components, a platform, a hammer, a spring, a catch and a holding bar. Now if you remove any of these five components the trap ceases to work, because each component is essential. Well scientists have noted that we see something similar particularly in the field of biology. There are numerous biochemical systems which contain several proteins, but if just one of those proteins is removed the system ceases to function. This fact cannot be explained by evolution and leads us to the conclusion that these systems and everything else in our world must have been designed by a Creator who had a clear purpose in mind.

c. Ourselves. So far we have noted that the existence of the universe and its complex design point us to the existence of God, but we also find evidence by looking closer to home. Someone has said that "we need God to explain ourselves" and that is so true. Just consider the fact that you and I are born with a natural sense of right and wrong. We all know that it is wrong to steal, to lie, to commit adultery or to murder. When we see someone being treated badly we automatically fell a sense of injustice, but where did this sense of right and wrong come from?

Well it cannot be explained by evolution. In fact if we are the result of a biological process governed by nothing more than chance, we have no basis for saying that anything is justice or unjust. The only satisfactory way to explain this moral aspect to our makeup is to believe that God, having made us in his own image, has put within us a sense of right and wrong. This also acts as a reminder that one day we will have to stand before this just and holy God, and explain our actions.

d. Jesus Christ. But perhaps the greatest evidence for the existence of God is the person of Jesus Christ. He came into this world and whilst here, provided us with undeniable evidence by his life and ministry, that there is a God and that he is his Son. If you would like to know more about Christ, you may find some of the following questions helpful.
