Failing does not mean defeat! It means we had the courage to try!
Whenever we make a mistake or don't do as well at a task, we have to remember that it is a natural part of learning.
Just like when we first learned to walk as toddlers. We fell down plenty of times until finally, one day, we took one step and then another and then another. Before we knew it, we were walking and the times of falling down were a distant memory.
When we feel like we've failed at something, we have to remember it is not the end of the world! We may feel sad for a moment but the key is not to stay there!
Take Peter, in the bible, for example. Peter definitely failed when he denied knowing Yehshua (Jesus) three times in a row. He was afraid of showing his true feelings about Christ and wanted to appear like everyone else that was against Jesus. That was a huge failure and he denied him repeatedly. However, when Peter repented of his actions and showed that he was sorry, Jesus, knowing that Peter was sincere, forgave him.
We are all human and that means we will all, at some point or another, fail or mess up at something. When we do, the key is to remember that we cannot stay there, wallowing in defeat or depression. We have to get back up, try again, and move forward.
God gives us the grace to overcome any negative feelings and thoughts when we experience these types of trials. Remember his unending love for us and that with him, all things possible, including overcoming our shortcomings and failures.
After all, he is the GOD who can do anything BUT FAIL!
