I'm not too young, too old or too unqualified for what God asks.
A Bible affirmation for self doubt, rooted in Jeremiah 1:7-8.
But the LORD told me: “Do not say, ‘I am only a child.’ For to everyone I send you, you must go, and all that I command you, you must speak. Do not be afraid of them, for I am with you to deliver you,” declares the LORD.
Jeremiah 1:7-8 · BSBReflection
Jeremiah protested that he was only a child. God told him not to say that, then promised to be with him. God doesn't accept your excuses about your limits, because He was never relying on them.
A prayer
Lord, stop me from talking myself out of what You've called me to. Be with me.
