John Ritenbaugh, focusing on John 17:3, maintains that to have eternal life we have to know God. Eternal life is to live a quality life as God lives, having developed an intimate relationship with God, living by ever-increasing faith. In order to develop this relationship, we must sacrifice time, becoming, in essence, living sacrifices. We must continually ingest spiritual food—the Bread of Life and the Word of God, seeking to be a part of the covenant made with David, containing the sure mercies of David. We must fully accept the sovereignty of God- internalize that sovereignty profoundly. In the Old Covenant there are no provisions for forgiveness of sin, or direct access to God by prayer or by the reception of the Holy Spirit. Faith comes from hearing the Word of God. Without hearing through sermons or reading the Word of God, there can be no faith and no understanding. Jesus Christ is our conduit to the Father. Getting to know God requires effort; it does not happen accidentally. It requires focused studying of God's Word on a continuous, daily basis. Truly, God has all the goodies. It is necessary to cultivate a genuine and healthy fear of God, a fear not natural to carnal man. It can only be developed by an abiding relationship with God, in which we learn both His strength and compassion. By continuous ingesting of His Word (enabling us to digest His precious doctrine), we humbly develop a close relationship with God. As we think in our heart, so we are. We should see God working in our lives and submit to His sovereignty, developing the kind of fear which draws us close to Him in humility. The fear of the Lord is the beginning of wisdom.
John Ritenbaugh, countering the naive assumption that the spirit of the law does away with the letter, insists that without the letter, there is no spirit because no foundations are possible. Writing the laws on our heart does not occur magically, but is a process (involving, prayer, meditation, learning and growing through life's experiences as our Elder Brother also grew in experience (Luke 2:40) We must walk as He walked (I John 2:6). The myriad examples given throughout the scriptures demonstrate for us (stretch out) the intent of the law. No scripture may say anything regarding a particular law, but examples (especially of Christ) will show God's will. The law appears in example form all over the scripture.
John Ritenbaugh marvels that human beings, having been given free moral agency, can accomplish what God had intended them to do all along. The apostle Peter, using the details of fulfilled prophecy (couched in David's psalms), convicts the crowd of their culpability (as we all need to be convicted) in the death of Jesus Christ. Peter clearly establishes the Messiahship of Jesus, showing His connection to David's prophetic psalms (such as Psalm 16) and David's lineage. The formula for receiving God's Holy Spirit—repentance and baptism is explored—and compared to current practice. The early church experienced a high level of cohesiveness by continuing in doctrine, fellowship, sharing meals, and praying together.
