When you have a purpose in life, you become grounded.

Philippians 2:5-8 You must have the same attitude that Christ Jesus had. Though he was God, he did not think of equality with God as something to cling to. Instead, he gave up his divine privileges; he took the humble position of a slave and was born as a human being. When he appeared in human form, he humbled himself in obedience to God and died a criminal’s death on a cross.

What is your excuse in doing God’s work?

Exodus 4:10 Then Moses said to the LORD, “O my Lord, I am not eloquent, neither before nor since You have spoken to Your servant; but I am slow of speech and slow of tongue.”

When God ask you to do something, it’s not because he ran out of people, it’s because its’ part of the purpose. Romans 9:20 But indeed, O man, who are you to reply against God? Will the thing formed say to him who formed it, “Why have you made me like this?”

When you don’t understand, don’t ask God questions, trust him. An excuse will not exempt you from doing what you are suppose to do.
