As a follower of Jesus, you are part of a royal priesthood. Like the priests of the Israelites, you have been given a responsibility to go into God's presence and make spiritual offerings to him through prayer on your behalf and on the behalf of others. In the second chapter of Malachi God reminds His priests that when this responsibility is done with honor and reverence for God life and peace follow. When the priests don't do this there are negative consequences. As modern day priests we are called to take up this responsibility to encourage life and peace for everyone.
