The reason most protestant churches today can get along well together is that they all agree when it comes to how a man is saved. Protestants, Catholics, fundamentalists and Pentecostals can work side by side in the major revivals and crusades of the 20th century. That which they hold in common is the exalted doctrine of man espoused by Erasmus, sharply defined by Arminius, made popular by the Wesleys, and given a final polish by the many religious leaders of our time.
Strange as it may seem there are many today who insist that they believe in salvation by grace, yet they insist that man's salvation is made operative by man's will and his own power to "make a decision for Christ" They argue that "God loves everyone equally". yet they are sure that He will send some people to hell. They affirm that the Bible teaches that the Creator of all things is surely omnipotent, but they are also quite confident that finite man can obstruct or control the will of God.
And the reason religion today is teaching such inconsistencies is that the natural religious man would rather worship the creature rather than the Creator (Rom. 1:25). The natural man seeks to establish his own righteous by his own good deeds (Rom. 10:14). He wants some of the glory himself He wants to feel that he is in control (1Cor. 1:26-31). That's why he feels that his works, will and worth have merit before a thrice holy God.
The Bible clearly teaches that salvation is totally of God and that no flesh should glory. In fact no flesh can glory because be has nothing in which to glory of "There is none righteous, no, not one... There is none that doeth good no, not one..." Rom. 3:9-20). The believer's glory is the Lord Jesus Christ.
