When God called Moses to do a task for Him, ( to lead the children of Israel to the promise land) Moses didn’t feel adequate to do the task, but God reassured him.
When God calls you to do a task for Him, He doesn’t ask you to be adequate, He asks you to be available.
Have I not commanded you: be strong and courageous. Do not be afraid or discouraged, for the Lord God is with you wherever you go. -Joshua 1:9
For we are His creation, created in Christ Jesus for good works, which God prepared ahead of time so much that we should walk in them. -Ephesians 2:10
