But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light… (1 Peter 2:9 KJV)
But ye shall be named the Priests of the Lord: men shall call you the Ministers of our God: ye shall eat the riches of the Gentiles, and in their glory shall ye boast yourselves. (Isaiah 61:6 KJV)
If we are the children of God, we are representing someone--someone who is All Powerful in all the universe. God called us to be in priesthood. When we go to our daily jobs, we just cannot be representatives ourselves in a work environment. We would be fired. Instead, we should representatives for the companies that we work for. In that same matter, when we'd decide to come into God's family, we are called to be ministers of God.
Being a minister of God doesn't to be within the church. God wants us to be spread His Words around to other people. Some people may think that being a Christian is too religious. Why? Some Christians may use too many big words or tackling their sins against the Bible instead of sharing the love of Jesus Christ with them. Being a Christian is having a personal relationship with Jesus Christ.
