Satan’s greatest weapon is deception rather than force, as shown through biblical examples like Eve, Samson, and Jesus’ warnings about the last days. Samson’s story is particularly instructive he didn’t fall all at once, but through gradual compromise, revealing that the most dangerous deception is knowing truth yet slowly stopping to obey it. The antidote is deep familiarity with Scripture and submission to the Holy Spirit, so that truth becomes so ingrained that lies are immediately recognizable, much like a bank teller who spots counterfeit bills by knowing genuine currency intimately.
