Others were with him on the road to Damascus; they saw and heard 'something' but Paul clearly heard in his own language (Hebrew) and saw glory He knew to be God...and not the God he served. 'Who are you?' Paul asked. Jesus replied, "I am the one you are persecuting." Paul did not defend himself or debate the matter. In fact, the focus remains on Jesus Christ as Paul relays what he saw and heard. Jesus said I showed up to let you know my plans for you. Jesus said you will tell people what I show you now and what I will show you in the future. Paul's summary: I was obedient!
And for a little motivation, consider some of the results of Paul's obedience. We surely benefit from the writings of Paul today, but as he 'walked' through life with eyes fixed on Jesus (so he could tell what he saw!), Paul had some wild successes. In a shipwreck (still a success), lives were saved, diseases healed, miracles witnessed and God glorified. On his journey to prison (and the will of God), fellowship was enjoyed and the purposes of God accomplished. The opinions of people were varied and unreliable; we must not be swayed by those either. Some said he was crazy, some said he was sinful and worthy of death, others said 'I am almost persuaded' and some saw nothing. It will be that way in our lives too. But in the end, the will of God will prevail. And His will is good. Look for Him today!
