How do Joseph's dreams relate to the gospel?

The dreams of the butler and the baker convey powerful truths about the gospel. The butler's dream signifies grace, restoration, and the efficacy of Christ’s atoning work for the elect. In contrast, the baker's dream illustrates the futility of self-righteousness, leading to condemnation. This duality serves as a warning and encouragement, reminding Christians of the importance of relying solely on Christ's righteousness for salvation, rather than their deeds, thus reinforcing the core message of the gospel.
