John Ritenbaugh indicates that we are being fitted as lively stones into an already formed Kingdom, being conformed to the image of Christ, who has been designated as the Cornerstone. As God's future priests, becoming living sacrifices, we will constitute God's department of health, education, and welfare, serving and helping humanity. The Israel of God becomes God's firstborn, being set aside as a chosen generation to help the High Priest, Jesus Christ. This role as Christ's assistants is what we are being prepared for, a role which will call for rigorous discipline. This rigor will enable us to be totally transformed from the inside out, bringing about a renewal of our minds and a change of character. We are appointed on men's behalf to deal with things pertaining to God. We will become the link between men and God. We will offer sacrifice, largely consisting of intercessory prayer. We have to have compassion, sympathy, and empathy with mankind, realizing the repertoire of our own weaknesses. Like Christ, we must learn from the things we have suffered, making us able to aid those who have been tempted. God has hand-picked or chosen us as forerunners because He loved us; we dare not squander this precious calling of training for the Royal Priesthood. The more we know God, the stronger and more insightful we will get, enabling us to build one another up in Godly love, thinking with the mind of the Father and Jesus Christ, with His Law written in our hearts.
John Ritenbaugh reiterates that humility is not an obsequious demonstration of low self esteem, but instead it is a proper estimate of our relationship to God, which is a choice to act and behave as a servant or slave. If we would follow Christ's example of humility, we would have automatic unity. We need to have both the inclination and the follow-through act of humility and lowliness of mind. We have to cultivate the same attitude as our Elder Brother as He esteemed others above Himself. Faith, praise, gratitude, thanksgiving, and humility all work together at building character. Perseverance in prayer and faithfulness causes our faith to increase and rescues us from pernicious worldliness.
In this sermon on biblical humility, John Ritenbaugh suggests that sacrifices of thanksgiving, praise, and gratitude are required of God's called out priests. By meditating on the physical creation, the human body, and God's Law, we prepare ourselves for prayer. God desires that we exercise gratitude and thanksgiving in order that: (1) We stay focused in the right direction (on the Creator rather than the created), (2) We develop and support the faith to please Him, and (3) We maintain a sense of humility—not an obsequious social skill—but a proper measure of ourselves with God, resulting in conduct following a biblical standard.
The apostle Paul predicted the end-time generation to be unthankful. As Christians, we need to buck this trend and show our appreciation to God and fellow man.
John Ritenbaugh focuses upon our future responsibilities as a priest in God's Kingdom, asking us if we are really preparing for this role. If we are not practicing being a priest right now,we will not be prepared. During the Millennium, the priest will be required to make a large number of mediating sacrifices on behalf of the people, mediating, reconciling, teaching, judging, and saving the remnant of Israel. The primary function of a priest is to assist people in accessing God- so that there can be unity with God. A priest is a bridge-builder between man and God. The sacrifice that God demands is a total sacrifice of time, energy, and service (in short, ones whole life) to that end. Nothing will prepare us to become a priest more than to commit our entire lives as a total living sacrifice.
John Ritenbaugh initially explores the work of Paul and Barnabas developing the church in the cosmopolitan city of Antioch, the location from where the term Christian originated. The twelfth chapter, an apparent flashback, focuses upon the execution of James (at the hands of mad Herod Agrippa), Peter's miraculous escape from prison followed by the dramatic death of Herod as a result of blasphemy, an episode showing the relationship between prayer and God's response. The episode also had the effect of driving Peter from Jerusalem. Chapter 13 begins a concentrated effort on the part of the Antioch church to carry the Gospel to the Gentiles through the efforts of Barnabas and Saul.
