Scripture: Hebrews 10:1-14
When we are called to be perfect, it is not so much that we are to be blameless and without fault but that we need to be just as we were made to be. We are perfect for the situation and the life in which we were placed. God created us for a perfect purpose in His plan. To be perfect is to be used of and by God for his purpose. Teaching, building, encouraging, supporting, speaking, caring, cleaning, whatever our calling might be.
When you understand what God wants you to be, you are perfect. When you are doing what you are called to do, it is perfect. You are perfect for that purpose.
