I don't understand

Thank you Lord for Proverbs 3 today. If you haven't read, it DO IT!! Normally I wouldn't even refer to Proverbs 3:5-6 because let's be honest. Everyone who's been a Christian for any length of time quotes that verse. But recently I've really been working on trusting HIM and not my own understanding. It's easier to trust HIM when I understand but when I don't understand that's when I want to panic. Verse 26 starts off saying "The Lord will be your confidence". Thank you Lord. I know I can come across as extremely confident at times but let me tell you that's not the case. I was recently in a situation where God asked me to say something and I was not confident at all. Actually I told HIM I didn't want to and to handle it without me. Needless to say, he won that argument. Well I was obedient (as far as I know) and it turned out like I thought (painful). Afterwards, I couldn't help but be upset with God. "See I told you, why did you make me do that?" Well when I read the first 4 chapters of proverbs this morning it all made sense. "My son (that's what he calls me) do not forget my law and let your heart keep my commands and if you do, even if it hurts at the time, you will have long life and peace." Then HE said " no matter how hard it is, never turn away from mercy and truth". He never said it would be easy or painless, just Trust HIM.
