Out of your mind but reasonable truth

Acts 26:24-32
Festus interrupted Paul's defence. "You are out of your mind, Paul! Your great learning is driving you insane."
What I am saying is true and reasonable. Paul said the king is familiar with these things. I am convinced that none of this has escaped his notice, because it was not done in a corner.
Paul said to Agrippa, "Short time or long - I pray God that not only you but all who are listening to me today may become what I am, except for these chains.
Agrippa laughs it off - he cannot afford to lose face with Festus or to offend the Jews by denying the prophets.
The governor and the king agree that this man could have been set free if he had not appealed to Caesar.
Why?
Paul served the Lord seems out of mind, but it is the truth that he preached the good news to many gentiles and Jews. What Paul has said are true and reasonable. It was not done in a corner, it could be proved and convinced.
Let us serve the Lord and preach gospel like Paul out of mind and driving to insane?
The gospel is true but it looks out of mind to unbelievers.
How?
Love the Lord with all my mind, my heart and all my strength! What I have believed are true, so I should let more people know it. Enthusiasm to love the God!
