But now, in light of the testimony of Scripture itself, one can know with certainty whether he is saved and will enter into heavenly glory. When Jesus dies for them, they also receive His Spirit, Who works in their hearts that life which Christ merited for them. Such are converted, confessing before God and man that they belong to Christ. And these have the assurance of the forgiveness of sin and the certainty of eternal life in heaven. None can take that certainty away from them.
None can destroy their faith.
These will not fall away from that grace of God once given to them. But even more important, this truth of Scripture that Jesus dies only for the sins of His own people, is the only truth which exalts the power and glory of the Name of God. Any other divergent view detracts from the glory of His Name. Any view of the atonement which suggests that the ultimate decision concerning one's salvation rests with man, detracts from the power and glory of God. He has absolute power.
