Heart over Skills - Being a leader is not so much about skills but about heart and availability to serve. I have come to see how God moulds, prepares, provides and guides you in ministry as long as you have the heart for God's people and are willing to avail yourself. It's about being "willing" and not worrying about the "able" part. Moses also started off feeling not confident as his ability to speak but manages to lead his people (Exodus 4:10-17):
10 Moses said to the LORD, "O Lord, I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue." 11 The LORD said to him, "Who gave man his mouth? Who makes him deaf or mute? Who gives him sight or makes him blind? Is it not I, the LORD ? 12 Now go; I will help you speak and will teach you what to say."
13 But Moses said, "O Lord, please send someone else to do it."
14 Then the LORD's anger burned against Moses and he said, "What about your brother, Aaron the Levite? I know he can speak well. He is already on his way to meet you, and his heart will be glad when he sees you. 15 You shall speak to him and put words in his mouth; I will help both of you speak and will teach you what to do. 16 He will speak to the people for you, and it will be as if he were your mouth and as if you were God to him. 17 But take this staff in your hand so you can perform miraculous signs with it."
God also assured Jeremiah in Jeremiah 1:5-8:
5 "Before I formed you in the womb I knew you,
before you were born I set you apart;
I appointed you as a prophet to the nations." 6 "Ah, Sovereign LORD," I said, "I do not know how to speak; I am only a child."
7 But the LORD said to me, "Do not say, 'I am only a child.' You must go to everyone I send you to and say whatever I command you. 8 Do not be afraid of them, for I am with you and will rescue you," declares the LORD.
