Just because you don't stand with a mic in your hand before a large group of people doesn't make you NOT an Evangelist. Just because you aren't leading a fellowship doesn't make you NOT a pastor. Just because you aren't articulating the word of God doesn't make you NOT a teacher. Just because you haven't planted a church recently or released ministry gifts or have not yet carried out the vision God gave you doesn't mean you aren't an Apostle any more.
You are what you are and that's what you will be positionally. Pastors pastor. Teachers Teach, Prophets Prophesy, Evangelists Evangelize and Apostles GO. They just do. It's who they are. If you wake them up at 3AM in the morning, they will default to who they are.
If you have a call of God on your life and you know it (don't clap your hands or stomp your feet) just live it out. Daily. Be the gift God filled you with. That can happen at the gas station. That can happen in the supermarket. That may happen at the doctors office. Anywhere. Anytime. You be, and the opportunity will provide itself. You don't need a building, acceptance, station or paid installation to carry out your mandate. A racehorse will race. You are called to run that race till you finish it.
So go, be, do, and don't worry about those stuck in traditions that try to hold you down. Your call is without repentance. You can't not be. There is no "Used to Be" in the Kingdom"
