On his way to arrest Jewish Christians in Damascus for heresy, Paul reports, "At midday, O king, along the road I saw a light from heaven, brighter than the sun, shining around me" (Acts 26:13). He falls to the ground, blinded, and hears Jesus Himself speaking to him, charging him with the mission to preach salvation to the Gentiles:
"...to open their eyes, in order to turn them from darkness to light,
and from the power of Satan to God,
that they may receive forgiveness of sins and
an inheritance among those who are
sanctified by faith in Me."
Here's that wonderful symbolism again--Paul, who thought he knew the light (righteous in his own self-righteousness)--is plunged into blinding darkness that he might have his spiritual eyes opened to the Truth. He receives his sight back three days later--a changed man, with God's Light in his heart, the revelation that Jesus died to give him God's own righteousness.
How fantastic that God seeks to reveal Himself to us personally, wanting so much for us to 'see' His heart, His invitation, the complete deliverance from darkness that He's provided through Jesus. I love these words in I Peter 2:9-10:
"But you are a chosen generation,
a royal priesthood, a holy nation,
His own special people,
that you may proclaim the praises of Him
who called you out of darkness
into His marvelous light;
who once were not a people
but are now a people of God,
who had not obtained mercy
but now have obtained mercy."
Marvelous light. What an invitation!
