The atheistic worldview (atheism) assumes that there is no God and everything in the physical universe came about only by natural means. This is a known as a naturalistic worldview (naturalism). In these worldviews, there is no basis for abstract concepts like logic or morality.
An atheist's beliefs and actions are inconsistent at best, because his worldview does not have a matching, consistent foundation. Instead, many foundational concepts rely upon a Christian biblical worldview, and as such does not make sense on several levels.
Logic and mathematics are abstract - they have no physical properties. They are purely conceptual and immaterial, but can be expressed and demonstrated in physical ways. Atheism cannot explain where logic or mathematics came from. Many atheists claim that math was an invention of man, yet 1+1 equaled 2 before man existed. Also, the rules governing these concepts never change. In the atheist's evolving universe, how can that be so? One has always been one...why haven't numbers evolved too? The Bible teaches that God created logic and mathematics and established their absolute rules.
Like logic and math, morality is also abstract. Again, it is the God of the Christian Bible that has defined the standard for good and evil, consequences of disobedience, and the requirements for forgiveness. Because atheism requires the absence of God, there can be no moral absolute or standard. Atheism insists that all life came about as a result of random chemical reactions over vast spans of time. In this worldview, humans are no more than just more highly developed animals with no purpose other than to procreate. Consequently, there is no higher authority to answer to beyond that which society has established. There are some societies, groups, and individuals that accept and practice behaviors deemed as immoral by other peoples. Sometimes, these disagreements lead to conflict, even war - but why would an atheist care? To remain consistent with his worldview, the atheist has no place to judge a behavior as either good or bad, nor has any reason or motivation to do so beyond self-preservation, because ultimately there are no eternal consequences. Why should an atheist hold murder against people when other animals do the same every day with impunity?
Atheists today have staked a claim on science. Several prominent atheists (Richard Dawkins, Bill Nye, Neil DeGrasse-Tyson, et al.) insist that one cannot be a good scientist unless they have an atheistic worldview. They claim that science has done away with the need for a God. Besides this being a preposterous assertion - there are many scientists that have made significant contributions that believe in God and are creationists1 - this is also illogical. For science to be performed properly, logic and mathematics are required. As discussed earlier, both of these were created by God. How can atheists depend upon God for the basis of their argument against God? Beyond that, science requires that the universe and its behavior remain consistent. If it were not, then a scientist's observations and measurements today may not be reliable tomorrow, much less next year...thereby defeating a requirement enabling science to be conducted. The universe created by God is consistent by design, while one arrived at by chance has no reason to be, nor guarantee of being consistent.
Atheism does not make sense. Science makes sense and is true only from a biblical perspective and obviously, morality has taken its source from the God of the Bible - the ultimate and absolute authority. God holds all people responsible for their actions, according to His law and commands, atheist or not.
The good news is that God loves "atheists" too! Today is a great time to consider God's gift of salvation through His Son, Jesus. If you want to learn more about Jesus, the Bible, and the Truth - then check out our other articles and useful links to external resources.
