How can I know that God really exists?
Sincerely,

Dear The Wonderer,

I could spend pages answering your question. The most difficult part of your question is trying to summarize the thousands of evidences for God’s existence. Please consider the following list as an abridged look at the topic.

Top 5 Reasons There is a God

1. The world was either created, or it came from nothing. If we are created, then there is a Creator. Consequently, one of the most basic rules of science is that something never comes from nothing (see an explanation of the first law of Thermodynamics here). The energy that exists in our universe had to come from somewhere.
2. Life never comes from non-life. All living things come from other living things. There is no such thing as spontaneous generation. Evolution teaches the opposite. Evolution states that all living creatures descend from one-celled organisms that were randomly created from inorganic material billions of years ago. That is scientifically impossible.
3. Life is complex. Complexity requires design - and consequently a Designer. Blood cells, dragonflies, oak trees, giraffes, etc. are all IMMENSELY complex and intricate things. It doesn’t make sense to say that they were randomly formed – they have far too much design.
4. Humans feel shame. Shame and guilt are uniquely human conditions that make no sense from an evolutionary standpoint. If we evolved to survive, and only to survive, there would be no reason for humans to have ethics. Why would we care about right and wrong unless we were created by a Creator who instilled these beliefs in us?
5. Humans hunger for religion. As a rule, human beings are religious. We crave spiritual knowledge and eternal wisdom. We often seek it in all the wrong places, but the fact still remains that we desire eternal purpose for our lives. A case can be made that there is nothing that we desire that can’t be fulfilled. We hunger; there is food. We thirst; there is water. We want companionship; there is the opposite gender. You are incapable of having a desire that cannot be slaked. This is more of a philosophical argument, but it can be argued that since we all seek God – God must exist.

I can guarantee you that I did not even begin to do the subject of proving God’s existence justice. If you would like to look at the issue in-depth, I recommend going to www.answersingenesis.org to get further scientific evidence for God. I also recommend the books Case for a Creator by Lee Strobel and Icons of Evolution by Jonathan Wells. And last but not least, I highly recommend the movie Expelled featuring Ben Stein. All of these resources will provide you with an intimate and compelling argument that God most definitely does exist.   SB
