1:20 without excuse. The phrase “without excuse” is, literally, without an apologetic” or “without a defense.” I Peter 3:15 instructs Christians to “be ready always to give an answer,” where the word “answer” is practically the same (i.e., Greek apologia). In other words, Christians do have an apologetic and ought to be ready to give it whenever someone attacks or questions their faith. Those who do not see the eternal power and nature of God in the creation, on the other hand, have no apologetic. They are “without excuse” (anapologetos) if they do not believe in our Creator God. The evidence is all around them!
