What saves me, God's goodness or my goodness? The church insists that each individual must activate his or her own salvation by being obedient and exhibiting proper piety.
If my compliance to requirements activates and maintains my salvation, then my goodness is the actual measure of sufficiency. No sophistic contention that accepting a free gift through acts of obedience is not a measure of personal achievement and goodness can ever change that reality. First and foremost, what I do, how compliant I am, is determinant, not what God or Christ do or have done.
Under such Orthodoxy, uncertainty is inevitable. The end of life experience will invariably bring up the question: Have I been good enough. For those in the church who adhere to the doctrine of eternal security, the question boils down to this: Have I exhibited a proper life which proves that I was really saved in the past. For others, who believe that salvation must be strictly maintained until death, the question becomes this: Have I done enough to remain saved. In either case, everyone dies unsure of salvation.
If the assurance of salvation is ever to be possible, the basis for that salvation cannot be my goodness, no matter how defined. If, however, salvation is based on God's goodness, i.e. His love, mercy, grace, and benevolence, the certainty of salvation is rooted in something that is sure and inalterable. Only then can mankind enjoy salvation for goodness' sake, not our own but His, the only measure which allows for security.
