C. I. Scofield, was one of the leading popularizers of dispensationalism. Scofield made this statement: “As a dispensation, grace begins with the death and resurrection of Christ. The point of testing is no longer legal obedience as the condition of salvation, but acceptance or rejection of Christ, with good works as a fruit of salvation." (Note on John 1:18, Scofield Reference Bible, Oxford University Press, 1909)
Lewis Sperry Chafer, a leading early dispensationalist, says that the dispensation of Law was a forsaking of a previous dispensation of grace, a reversal in the progress of the dispensations. “When the Law was proposed, the children of Israel deliberately forsook their position under the grace of God which had been their relationship to God until that day, and placed themselves under the law."
Chafer went on to say, "The essential elements of a grace administration – faith as the sole basis of acceptance with God, unmerited acceptance through a perfect standing in Christ, the present possession of eternal life, an absolute security from all condemnation, and the enabling power of the indwelling Spirit are not found in the kingdom administration. On the other hand, it is declared to be the fulfilling of ‘the law and the prophets’, and is seen to be an extension of the Mosaic Law into realms of meritorious obligation." (Dispensationalism p.416).
William Evans (Outline Studys of the Bible, p. 34) says:
"This is sometimes called the Age of the Church, or the Church period. The characteristic of this age is that salvation is no longer by legal obedience, but by the personal acceptance of the finished work of Jesus Christ, who by his meritorious ministry has procured for us a righteousness of God’."
The original “plan of salvation” was pure WORKS (Gen. 2:16-17), and in the Millennium the last plan of salvation is again pure WORKS (Rev. 22:14), contrary to every immature, milksop, Baptist baby in your town or city. Genesis 3:22 corrects the kiddies. (Ruckman, Peter. Ruckman’s Bible References: Personal Notes on Salient Verses in the Bible, p. 7)
In the Old Testament, you find salvation before the Law by grace through faith and under the Law by faith and works… (Ruckman, Peter. Body, Soul, and Spirit. 1986, 1997, p. 12)
If the Lord comes and you remain behind, then start working like a madman to get to heaven, because you’re going to have to. You have entered a period of time called “The Great Tribulation,” and the plan of salvation in the Tribulation is faith in Jesus Christ plus your own good works. (Ruckman, Peter. Millions Disappear. 1989, p. 23)
Before the Rapture, you could have been saved by grace through faith plus nothing (Ephesians 2:8-9), but one minute after the Rapture took place you must get out the Ten Commandments and the Golden Rule and start learning them, because you’re going to be judged by them (Matthew 25:31-46). (Ruckman, Peter. Millions Disappear. 1989, p. 23)
It will take faith in Christ’s shed blood, plus works—exactly as in the OT it took faith in shed blood and works. (Ruckman, Peter. Millions Disappear. 1989, p. 26)
Just look at some of the posting right here on the Baptist Board regarding the salvation of the Old Testament Saints and you will see all sorts of differences between OT and NT salvation.
