“As you come to him, the living Stone —rejected by humans but chosen by God and precious to him—5 you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.” (I Peter 2:4-5 NIV)
All true Christians are priests. Therefore, do not pay any regard to those who claim to have special priestly authority above the common lay person. They are liars and deceivers who are usurping the power that God has given to all of his saints.
But what is a priest? A priest is someone who can come to God directly, talk to God, and God will listen to him. All those who truly believe are priests (I Peter 2:7,9). This is an impressive privilege that God has given us through the blood of Christ! We are part of a spiritual house that God is building. Our job is to “offer spiritual sacrifices acceptable to God through Jesus Christ.” We do this through our prayers and our good works “which God prepared beforehand.” (Ephesians 2:10)
Therefore, let us constantly perform our priestly duties
“brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus, 20 by a new and living way opened for us through the curtain, that is, his body, 21 and since we have a great priest over the house of God, 22 let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscienceand having our bodies washed with pure water. 23 Let us hold unswervingly to the hope we profess,for he who promised is faithful.” (Hebrews 10:19-23 NIV)
