Satan has managed to stop Christians from keeping the commandments of Jesus Christ. When Christians do not keep the commandments of Christ and His Apostles the new covenant ceases to operate.
How has Satan managed to accomplish such wickedness in the churches? By planting a false concept of salvation in the minds of the pastors and teachers.
The erroneous idea that Christians are not obligated to keep the commandments of Christ and His Apostles may date from first-century Gnosticism and account for the exhortations found in the Book of First John.
