I don't think Christ wants us putting ourselves down. If He forgives me in all my many, many mistakes, shouldn't I pray to Him for Making Mistakes Grace, so I could forgive myself for not being perfect and making mistakes? You bet and I need to do so next time!
Example of a Brief Prayer
But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they. Acts 15: 11
I was with someone who was scooping up some free popcorn. They didn't ask me if I wanted any. The person told me that I should get a bag of popcorn and then took it from my hands. They wanted me to get the popcorn for them to eat later.
It's such a silly thing, but it really did irritate me. Didn't that person think about whether I wanted some or not? Couldn't they have asked me if I wanted some before they took it from my hands? I found myself getting frustrated at that person. Then, it popped into my mind that that's not what Christ wants of me. He wants me to be gracious to those who irritate me, but I was too frustrated to be gracious at that moment.
