When posed with the question, "Who said that Jesus is Lord and God?," I paused. I tried to remember when Jesus confessed Himself as such, but I knew in my heart He never said it as plainly as "I am Lord and God."
Instead of saying it outright, He let people discover and come to believe the truth for themselves. Then He affirmed their statement when they believed. The biggest two examples are in Matthew 16:13-20 and John 20:26-19.
In Matthew before Jesus died, He asked his disciples, "Who do you say that I am?" Simon Peter replied, "You are the Christ, the Son of the living God." And Jesus answered him, "Blessed are you, Simon Bar-Jonah! For flesh and blood has not reveal this to you, but my Father who is in heaven."
Then in John, after Jesus rose from the dead, the disciple Thomas said to him, "My Lord and my God!" Jesus said to him, "Have you believed because you have seen me? Blessed are those who have not seen and yet have believed."
I think it's truly a beautiful way of revealing Himself. It's gentle, not forceful. It's a gift from God, to be blind and then have our eyes opened to the truth.
