Fear is crippling. I work with a lot of people who are completely crippled by fear. Fear can be our biggest enemy. In the text Paul is encouraging us to have no fear in sharing the love of God.
Could this be a message written for people today. Now it is so difficult to share your faith. We live in a time where having faith of any description is looked at badly. Not only that it's seen as almost the realm of the stupid. It's not possible for people of real intelligence to have faith.
In this climate it strikes me that having a spirit of fear is immobilising. What you want is freedom. Freedom to be the person God create you to be. Freedom to share your faith. Freedom to show love to others.
Can this be applied to other areas of our life? Yes. God does not want us to be halfhearted in life he wants to put our talents and gifts to use not to have fear an hide them.
Be confident. Stand strong. Be brave. God is with you.
