What has God healed you of? What has he delivered you from? That healing and that deliverance is not just a work he wants to do in you. It’s a work he wants to do through you.
There are likely people all around you who could use the encouragement they would receive from hearing what God has done in your life. They need to hear your story so they can believe the God who did it for you, can do it for them.
You don’t need a stage or a platform to use your voice to impact someone’s life. Invite a girl to coffee. Set up a lunch date. Make yourself available and then just watch and see how God leads you to lead another to victory.
