Here, in the Old Testament, we are told that God is looking for a kingdom of priests. In the New Testament scripture of I Peter 2, we are called to be a royal priesthood. There are many references in the Bible that mention that a priest is one who enter the Holy of Holies. He is one who draws near to God. But something happened on the day that our Lord and Savior Jesus Christ died on the cross of Calvary.
Scripture says that veil in the temple was torn from the top to the bottom.
It had to be an act of God. Before, it was only the priests who could enter into the Most Holy Place. Now, because of what Christ has done on the cross of Calvary, you and I have access into the presence of God. And this is done when we become worshippers. So, in essence, what Scripture says, both in the Old Testament and the New Testament, is that God wants us to be priests.
