Calling is who we are. It is the purpose that God birthed within us.
Have you ever just felt unfulfilled like you knew you God was calling you to do more but you did not know exactly what it was you were suppose to be doing? This was exactly how I felt! I was at a job I pretty much hated. He was compelling me to do more. I could feel it in my spirit. I thought I knew what I wanted to do with my life, but God had other plans for me.
Calling is a purpose that God placed in your life in use of the gift and passion that He has placed in you from the very beginning. It is about using those gifts to share God's love and letting people know that they are not alone in their struggles. It's a beautiful marriage between using your passion towards the people that God is passionate about.
