Arminianism

Firstly, Spurgeon held that Arminianism does not merely affect a few doctrines which can be separated from the gospel, rather it involves the whole unity of Biblical revelation and it affects our view of the whole plan of redemption at almost every point. He regarded ignorance of the full content of the gospel as a major cause of Arminianism, and the errors of that system then prevent men from graspingf the whole divine unity of Scriptural truths and from perceiving them in their true relationships and in their right order. Arminianism truncates Scripture and it militates against that wholeness of view which is necessary for the glory of God, the exaltation of Christ and the stability of the believer.
