“And for three days he was without sight, and neither ate nor drank” (v9). Saul had been aggressively persecuting Christians until he was stopped by Jesus himself. His encounter with Christ left him blind, and he didn’t receive sight again until he submitted to the prayers of Ananias, a disciple in Damascus. Saul (Paul) became dependent on his new friends for his safety and had to earn their respect; meanwhile, he learned “how much he must suffer for the sake of My name” (v16).
Saul had to lose himself – his vision, his power, his reputation – to serve Christ; he “preached boldly” because Jesus became his one goal (v28).
