Road Signs all basically having a common message (Be safe, get there safely).

So, too, the Miraculous Signs in the Book of Acts have the same common message:  Jesus is the One Way to be Safe with God and enter the Kingdom.

Here a Different Sign (healing) leads to the Same Message:  It's Still All about Jesus!  So turn to Him.

Physical healing points to our DEEPER need:  Spiritual Healing - eternal Restoration with God.

So turning to Jesus (repentance) is a positive thing!...because by turning to Jesus, our sins are washed away, our conscience is cleared, and refreshment comes!   Repentance is GAIN!
