What is the significance of baptism according to 1 Peter 3:21?

In 1 Peter 3:21, baptism is described not merely as a physical act of washing but as a spiritual reality that reflects our union with Christ. It represents an inward transformation where believers, having been immersed in Christ's death and resurrection, publicly declare their faith. Baptism is an outward sign of the inward faith granted by God, and like Noah's ark, it symbolizes protection from judgment. It serves as an answer of a good conscience toward God, affirming trust in His promises. This aligns with the reality that believers are saved not by the act of baptism itself, but through the spiritual significance it holds as it points to the greater reality of salvation in Christ.
