Why should i take the consequence?

I felt pretty bad after this Sunday worship. Actually, i should say that i felt awful.
Why? I led a pretty awful worship. It made me so upset because there was empty during the worship. That meant there was no connection to God.
My husband and my daughter told me the keys were too high, and a young kid's mom came to me asking me to add some allegros songs. I was totally smashed.
So i started to make an excuse for myself, I searched the file in my brain. Was there anything that i could accuse for the failure? Finally, there was one reason that i could blame on. I felt much much better.
I went to God. He told me clearly. I was the leader so i was responsible for the failure. I told Him that it was not my fault and i gave Him the reason. But He still gave me the same sentence.
With a heart broken, i admitted it was my mistake. God showed me that Jesus was the lamb of God. Jesus represented us to die on the cross. He was the leader so all the sins ( condemnations or reponsibilities) were on Him. I did not need to hide . Just confessed and recognized how weak i was. God would not condemn or be mad at me because He loves me and He knew me.
After acknowledging it, I was in a rest. And my heart full of thanks!
Actually, after this event i wanted to quit the worship leader. I thought i was not qualified. I was really too old for the young kids. I asked God. He did not ask me to stop serving Him so i will still stand on the platform to lead the worship. Even though this bad experience made me fear. With God, there is nothing impossible to me. And God asked not to seek for people's praises but His! Because people's praises just like smoke, it will be gone immediately. And God's lasts forever. Praise my comforter the almighty one!
