How many times have you started to do something, and an alarm in your head said, "Don't do that!" but you did anyway?
You always seem to know what the right thing is, even if you don't always do it.
Where did that sense of "rightness" come from? This is the third evidence for believing in God: we all have a moral standard that is higher than we are.
Leith Samuel writes in HIS magazine, "Many missionaries point out that the heathen know more than we think. They know that there is a God. There are no atheists among heathen tribes. There has never been discovered upon earth a tribe of people, however small or depraved, which has not believed in some kind of god or had some system of worship... the heathen in so-called primitive tribes know that they have sinned. When a Christian comes to them and talks about sin he often finds ready acknowledgement that this is true. The heathen seem to know that their sins must be punished. They seem afraid of punishment, and afraid of death (as are most men everywhere). They know that sin must be atoned for, and they seek ways of appeasing their angry deities."
Moral codes and ethics vary from culture to culture and from person to person, but every human being has an innate moral standard. Where did this moral standard come from?
Since it is impossible to invent something that is greater than we are, there is only one reasonable answer: There is a moral Creator who put this standard in us!
