How do we know the dying thief was saved?

The certainty of the dying thief's salvation is affirmed directly by Jesus in Luke 23:43, where He promises, 'Today you shall be with me in paradise.' This declaration by Christ serves as definitive proof that the thief was saved. Despite his lack of good works, baptism, or theological education, his faith in Jesus' identity as Lord secured his salvation.

It's crucial to understand that the thief's faith was not based on a complex understanding of doctrines or rituals; rather, it was his recognition of Christ's lordship and his own sinfulness that demonstrated saving faith. His acknowledgment of Jesus as a sovereign being capable of forgiving sins highlights the core of the gospel — that salvation is by grace through faith, irrespective of one's background or actions.
