In our weakness

So today I read about something in my devotional that was truly amazing. it talked about that in our weakness, we can take delight because God is strong. And that is something that is very encouraging to me personally, because a lot of the time I feel very weak or unable to be an effective servant for my Lord. And today's devotional reminded me of something I was thinking about yesterday night. I was thinking why are a lot of us afraid to witness or to teach and share God's word. That part is probably the easiest part of our whole ministry, why? Because all we have to do is open our mouths and God does the rest. How many times in the bible does God calm our worries by saying that you don't need to worry about what you are going to say. Because it will be me speaking through you to my people. And I thought this insight really fit with the issue of our weakness and God's strength in it. Because personally every time I teach my hear races and I feel almost faint, but then this assuredness washes over me an I know its not me speaking. The Holy spirit empowers us when we speak and witness, we needed worry about what to say. But only to make sure we open our mouths to let those word's come out.
