About four months ago I got the opportunity to preach for the very first time ever. When the opportunity was first mentioned I was very excited, but the closer the date got, the more nervous I got. When I was in high school I could barely give a book report in front of the class. So I think it is pretty obvious how nervous I must have been. The night to preach was there, and I was sitting in the sound room at the church and my youth pastor asked if I was ready. I told him I was super nervous. So he directed me to this proverb:

To the man belong the plans of the heart, but from the Lord comes the reply of the tongue.(Proverbs 16:1)

This verse was definitely a huge help.  The way I understand it is that as people can plan to say whatever we want to, and no matter how studied up we are, the Lord will still direct what comes out of our mouth, because it is for His glory and not our own.
