One of the main differences is seen in the doctrine of eternal security. These and other similar questions will be asked as we compare the scriptures with the doctrinal statements of the day. But by the grace of God one who has fallen into sin may by y true repentance and faith find forgiveness and restoration. However, this impulse must be consciously nurtured, and careful attention given to the requisites and processes of spiritual development and improvement in Christ-likeness of character and personality. Without such purposeful endeavor one's witness may be impaired and the grace itself frustrated and ultimately lost.
All true believers endure to the end.
Those whom God has accepted in Christ, and sanctified by His Spirit, will never fall away from the state of grace, but shall persevere to the end. The main difference between advocates of eternal security and those who believe salvation can be lost hinges on the role God plays in our salvation. Those who adhere to eternal security base their belief on the sovereign power of God to keep his people forever. Those on the opposite side believe that once God saves it is up to man to continue in his salvation by his good works. If however our eternal state is dependent totally upon the action of God toward man we can never fall because God in His omnipotence does not possess the frailty needed to let us go.
