God doesn't call the qualified, He qualifies the called.
I am a hot mess. I am a high anxiety, tightly wound, overly emotional female that has a crying fit at least once a week. Sometimes it is about things that are a big deal, but other times I might find myself crying and eating a candy bar because I forgot to check the mailbox. I complain and worry, I sin and am sometimes selfish, I don't always say the right words, and I am afraid of things that normal people don't even think twice about. I have very little patience, and I don't function well in disorganization. But if there is one thing that I have learned with certainty, it is that God will take the most unlikely, unqualified, broken mess of a human being and give them a task that is only possible through Him.
I am not a writer. I am not eloquent in how I speak and can barely stay on one topic for longer than a few minutes. My grammar is not always correct and I can't ever figure out where to use a colon versus a semicolon. Not once in my entire life did I think, "Hmmm, I would be a good writer." But my plans didn't take into account His power and purpose.
Let's be real here. God doesn't need us. He is all powerful and can make the entire world bow down in worship anytime He wants. But He doesn't, because He wants us to choose Him of our own free will. He wants to change the hearts of sinners and transform us into vessels that tell the world about Jesus with passion. All He wants from us is a willing heart. He wants us to be ready and willing to do His Work, not begrudgingly or out of guilt, but simply because we want everyone around us to know that this awesome God loves us. He wants us to excitedly tell people about this God who became flesh and took on our punishment, giving His very life so that we can know Him. He wants us to have a fire within us for Him and a boldness that can only be explained by His hands. So, He pours His Holy Spirit into us and over time this causes an eagerness to blossom. This eagerness, He then uses to speak into the lives of people around us and testify about His goodness.
It's easy to let the enemy make us think that there is nothing we can do to grow the Kingdom of God, but I promise that God has the desire and the ability to work in us and through us for mighty things. He has a purpose for you and if you are willing to give in to His calling for you, one day you will look back and stare in awe at His goodness and grace. What is He calling you to do that makes you want to run the other way in fear? Pray for Him to give you the courage to follow Him wherever He leads.
