"If i say, "i will not mention Him, or speak any more in His name," there is in my heart as it were a burning fire shut up in my bones, and i am weary holding it in, and i cannot."
There might be times when we dont want to speak up in the name of the Lord for various reasons and in numerous circumstances, and I think Jeremiah shows us its ok to feel that way.
But as children of God we have been given a new heart of flesh that loves the law of God. And who also have the very Spirit of God living in us.
Plus the fact that the one who spoke the universe into being has verbally commissioned us to go and make disciples, means that ultimately we cannot hold back from confessing Jesus Christ as LORD to those around us.
