Gun Slinger (Chick tract)
Gun Slinger is a Jack Chick tract whose description is "A hired killer trusts Christ and, at death, goes to heaven. But the law-abiding marshal who hunted him rejects Christ and goes to hell. Clearly shows that salvation is through grace, not works."
In an old west town, Terrible Tom comes to town. Tom is a hitman who is hired to kill the town preacher. Upon hearing the preacher's sermon, Tom has an attack of conscience. Instead of killing the preacher, Tom falls on his knees and accepts Jesus Christ.
An hour later, Terrible Tom is arrested by the town marshall, who describes himself as "the most honest, law-abiding man in this whole territory." In an ironic twist, the marshall is killed by rattlesnakes. Since the marshall did not accept Jesus, he goes to hell, while Terrible Tom goes to heaven.
This tract starkly lays out Chick's fundamentalist philosophy that it does not matter how good or bad you are.
