“But, beloved, we are confident of better things concerning you, yes, things that accompany salvation, though we speak in this manner. For God is not unjust to forget your work and labor of love which you have shown toward His name, in that you have ministered to the saints, and do minister. And we desire that each one of you show the same diligence to the full assurance of hope until the end, that you do not become sluggish, but imitate those who through faith and patience inherit the promises” (Hebrews 6:9-12).
The false doctrine of “Once saved, Always saved” is founded upon the lie that there is nothing other than a moment of faith that is all that is necessary for anyone’s salvation. There is no other divine condition(s) attached to God’s offer of salvation in Christ than that moment in time in which you pray the “Sinner’s Prayer” (which, incidentally, cannot be found anywhere in the New Testament).
According to this heresy, works of obedience to God are not necessary for you to go from being lost to saved or to remain in a saved state. In other words, there is not one single thing that accompanies salvation.
Because an inspired writer of Scripture cannot be wrong in doctrine, the words of Hebrews 6:9 are true—there are things that accompany salvation. Therefore, any doctrine which teaches or implies otherwise—as “Once saved, Always saved” does—is categorically false.
As the passage above indicates, work and labor of love (v. 10) are essential to remaining saved. The need for spiritual diligence, not sluggishness/laziness (v. 11-12) is essential, if a Christian desires to inherit the promises God has made concerning eternal salvation.
Be not deceived: God in His word clearly states there are things which accompany salvation. Without your work, labor of love, and spiritual diligence, your eternal salvation will be lost.
