When you were baptized, the priest rubbed holy oil on your forehead and anointed you "Priest, Prophet and King." Did you know that you're a priest, a prophet and a king?
As a prophet, you have been made a witness. Christ called his disciples to be fishers of men and to be light of the world and salt of the earth. Be light and salt to those in your local community, in your region, and to the ends of the earth. Study the Word of God and give the gift of encouraging others.
As a king, you have been made eternal. Your salvation comes by God through faith for works, and you have been given a heavenly inheritance. Store up for yourself a treasure in heaven by giving generously, serving joyfully, and loving unconditionally. Get involved in kingdom building works that will transform this world.
I'm going to be honest here... Sometimes when I think about these things -- trying to be holy, being a witness for Christ, serving others -- the devil tells me that these things are boring, that when I do these things I'm not going to have any fun, that I'm going to miss out on life. (This tactic goes all the way back to the Garden of Eden by the way.) So in order to combat these thoughts, whenever the thought pops up that a relationship with God is lame, I'm going to read an exciting Bible story, the Book of Acts is chock full of them. If you can relate, join me in reading some thrilling stories from our faith. Following Christ doesn't cause me to miss out on life -- it grants me access to the life I've always wanted.
