The concept of spiritual priesthood emerges as a profound responsibility for those who are converted and united with Jesus Christ. As He declared in John 2, "Destroy this temple, and in three days I will raise it up," Jesus positioned Himself as the central focus of worship, replacing the physical Temple. Since we are in Him, we become part of this spiritual temple, vital to the worship of God. Jesus Christ, as the Head and High Priest of this temple, integrates us into His priesthood even now, before the resurrection. His work becomes our work, binding us to Him eternally as we follow wherever He leads. This spiritual priesthood connects us to a divine family and purpose. Upon conversion, regardless of ethnicity, we become spiritual Jews through the circumcision of the heart, united in Christ. As part of His body, we share in the responsibilities of His priesthood, preparing to assist in the salvation of humanity during the Millennium under His leadership. This role demands preparation now, as we are called to develop the character and qualities necessary to serve as priests under Jesus Christ. The Bible reveals a progressive development of priesthood, beginning simply and becoming more complex over time, reflecting God's pattern. From early instances where individuals acted as priests for their families, the role expanded to encompass the nation and ultimately the church. As disciples and learners of Christ, we are being shaped into priests of the Most High God, tasked with significant future responsibilities. This calling urges us to embody priestly characteristics in our present lives, aligning our actions and character with what God expects of those who will serve directly under Jesus Christ upon His return.

The concept of a spiritual priesthood carries profound responsibilities, rooted in the call to holiness as exemplified by God Himself. Holiness, far more than mere morality, defines God's uniqueness—He is separate, set apart, and beyond human comprehension, evoking awe and reverence. As God is holy, so are we called to strive for holiness, though in this life we can never fully attain His level of purity. Yet, through God's grace, the righteousness of Jesus Christ is imputed to us, enabling us to approach His presence and engage with Him intimately. This call to holiness is especially significant for those in a priestly role, as they serve as living reminders to all that everyone must pursue holiness as God is holy. Under the New Covenant, we are all part of a kingdom of priests, created in the image of Jesus Christ, bearing the spirit of God. This places a higher expectation on us compared to the priests of old, who lacked such spiritual empowerment. As priests to one another, we are visible and audible links between God's initial call to holiness and its ultimate fulfillment in His Kingdom, serving under our High Priest, the Lord Christ. The importance of holiness in this intimate association with the Father, the Son, and each other within God's family cannot be overstated. Priests, historically and spiritually, are messengers of the vital responsibility to reflect God's character. Their lives, hedged with restrictions, are designed to maintain a state of holiness, representing God before the world and the church. God demands a high level of holiness from us, urging us to conduct ourselves with the utmost care in attitude and behavior, striving to be as clean and distinct from the world as possible in a righteous way.
