When God needed to turn Saul’s life around, he used a supernatural light, an unseen voice, and temporary blindness to get Saul’s attention (Acts 9:3-9).
Some time later, Saul (Paul), under the power of the Holy Spirit, did the same thing to a guy named Elymas. Elymas was supernaturally blinded for a time so God could get his attention (Acts 13:9-11).
These two accounts have amazing similarities.
Before both of these occurred, Jesus healed a blind man. When questioned about it, the man said, “I once was blind, but now I see.”
What he said literally about Jesus healing him, we can say figuratively about Jesus saving us.
