Commentators emphasize that the spiritual strength of the "young men" is not their own. Their ability to overcome the evil one comes directly from the fact that "the word of God abideth in you." Scholars explain this "word" can refer to Christ Himself (the Logos) or the Gospel, which works powerfully within a believer. The key principle is that true spiritual power for service and victory over temptation is rooted in God's Word living inside a person.
