Genesis 15:1 

After this, the word of the Lord came to Abram in a vision: "Do not be afraid, Abram. I am your shield, your very great reward."

meaning of afraid: Filled with fear or apprehension 

When fear grip our hearts, our response to His calling usually is : I am not capable, use someone else.  

We should realize that fear desire is to stop us from fulfilling God's purpose. God's word reassure us, strengthen us and increase our faith to make that step. I pray you will be encouraged. Take the limits off and trust His provision.

God Got you!!!!
