Why are physical miracles not enough for salvation?

Although Jesus performed many physical miracles, these acts alone do not secure salvation for individuals. In John 6:66, we see that many disciples turned away from Jesus despite having witnessed His miracles. This points to the reality that external signs, while significant, do not produce saving faith. Instead, salvation is a work of God where one must be born again (John 3:3) and receive spiritual life through the Holy Spirit. The transformative work of Christ in a believer's heart, producing faith and repentance, is essential for true salvation, which physical healing cannot provide. Thus, while miracles reveal Jesus' power, they do not equate to the spiritual regeneration necessary for salvation.
