Bottom line: A compromised calling + a corrupted character = a collision course with a sinful disaster.
Samson is the picture of a believer who gets on a collision course with a sinful destruction. Samson compromised his calling by not living a life separated from sin and to God. He regularly chose to sin sexually, pridefully, disrespectfully, selfishly, etc. Samson literally became imprisoned in Gaza because he first became a prisoner of sin. The lesson we learn from Samson is that sin will not only eventually bring destruction, but it will predictably bring destruction. The course of sin in our lives is enticement, control, and betrayal. Sin will do to us metaphorically what actually happened to Samson. Sin will blind us, bind us, and make our lives grind.
