Scripture:

Acts 26:15-16And I said, ‘Who are you, Lord?’ And the Lord said, ‘I am Jesus whom you are persecuting. 16 But rise and stand upon your feet, for I have appeared to you for this purpose, to appoint you as a servant and witness to the things in which you have seen me and to those in which I will appear to you,

Observation:
Paul is testifying before King Agrippa as Paul has appealed to Caesar as a Roman citizen. The Jewish people were seeking to have him tried and put to death for preaching Jesus. Paul with a moment to give a legal defense does not reach into every crevice of Jewish law and regulation, but instead looks to where the gospel intersected his life, he shares his story. 
Application:
I should never forget the power of my testimony. Once I was dead in sin but Jesus has brought me life! There’s no argument or explanation that could bring someone to faith, but the power of testimony has compelled many. 
Prayer:
Lord teach me more and more to live a life that testifies to your gospel work in me. Open my eyes to opportunities this week and even today to be sharing your story in my life with someone.
