Mosiah 13:3

"Touch me not, for God shall smite you if ye lay your hands upon me, for I have not delivered the message which the Lord sent me to deliver; neither have I told you that which ye requested that I should tell; therefore, God will not suffer that I shall be destroyed at this time."

Abinadi knew who to serve. He did not fear the threats of the King and Priests. Rather, he trusted in God. Abinadi was spared so he could finish the message he was commanded to share. He had so much faith and was protected by divine help. He knew what he was supposed to do, and he did it.
