Antinomianism is addressed in Romans 6-8: These people distorted the message of salvation by grace, into ungodly and licentious living and saying, “Let us sin so grace may abound.” Enthusiasts in 1Corinthians 1-2: They said “the age to come” is already here and we have already been spiritually resurrected to heaven and are like the angels. Gnostics in 1Corinthians 15: They believed the spirit is good and the body is evil. The body will not be resurrected; only the spirit is immortal. Docetism is addressed in the epistles of John: Their teaching was that the Lord Jesus Christ was not truly a human but a spirit in a visible form.
Our Lord Jesus gave the best description of Christianity in John 17:21. “That they all may be one; as Thou. Father, art in Me, and I in Thee, that they also may be one in us: that the world may believe that Thou hast sent Me.” That means Jews and Gentiles are one in Christ, one body in the Lord.
James Houston was the founder and principal of Regent College in Vancouver, BC. He said, “Prayerfulness is the breath of relationship, and an antidote to the godless poison of secular psychoanalysis. Prayer becomes intertwined with the desire to be filled with the Spirit as we relate to others. I have found it impossible to separate prayer from friendship.”
The concluding chapter of Romans makes the teaching of the book very personal as the first two verses are commending Phoebe and linking her with Paul’s commission. Verses three through sixteen are greetings to thirty-six Roman believers. Warnings about false teachers are given in verse seventeen through twenty. Then greetings from fellow-workers are passed on to the saints from verse twenty-one through verse twenty-three with a pre-doxology in verse twenty-four and the book is concluded with a doxology from verse twenty-five through twenty-seven.
