Inadquate. [ Jeremiah 1 v 6-7 ]

I have been preaching for many years so why was I feeling totally inadequate earlier this evening, as I was preparing to go out to preach. I felt I should not go , give up preaching. I had I thought, my sermon ready, but as I went over it, it did not seem to have a meaningful ending, I started wrecking my brains ,praying for a useful illustration, but nothing came. Preaching is not easy but can be very rewarding, I sometimes preach the same sermon twice. but usually I prepare a fresh sermon. So here was I feeling like giving up on preaching , but then I did my daily Bible reading from Jeremiah ,and we have the prophet saying to God, I cannot speak, for I am a child, he felt inadequate, so I was in good company, so God agreed with him, no He didnt, He told the prophet, say not, I am a child, for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak. [Jeremiah 1 v6- 7 ] So with all my feelings of inadequacy I went and preached and God helped me, and for that I am grateful.
A prayer / Dear God help us to be faithful in those tasks You have entrusted to us, help us to trust You for the grace we need , in Jesus name . Amen ./
