Brother Santana,
Saul's whole world was shaken and don't think for a moment that he didn't know the Lord!! He did say, "Who art thou, Lord?" When a Jew comes face to face with the Risen Christ, I believe they know exactly who He is!! How long does it take for someone to "know" the Lord? In an instant? Three days? Five years? (huge grin) In an instant!!
God blinded him and he couldn't see physically but yet God showed Him visions... God showed him Ananias coming in and laying hands on him to receive his sight. And God showed him how much he would suffer for Christ's sake (how could God do that if Paul didn't know the Lord?). And Paul prayed!! That was the first thing Jesus told Ananias to comfort him, "Behold, he prays."
But Santana, please remember that the blind man who had his world rocked and who prayed on Straight Street was NOT the same man who finally wrote, "I have fought the good fight, I have finished the race, I have kept the faith" (2 Tim 4.7).
I can only hope and pray that the woman I am today (in all her faults and failures), will not be the same woman when I reach the end of my days. Paul DID know the Lord and grew closer and closer to him as his life went on. Praise God... as it should be!
Take hope as well!!
