The fact salvation is a process means it is not an unconditional one and done deal for all time regardless of how the Christian lives his life. Since salvation is a process is why the Christian is told to be faithful unto death (Rev 2:10). The Christian is to run the Christian race and cannot stop until the race is finished, not fall short, (Hebrews 4:1). Phil 2:12 “work out your salvation” is a ongoing sustained work not a one time, unconditional deal.
The justification of Abraham was a process beginning in Genesis 12 with his obeying God in leaving house, land and kindred to Genesis 22:12 in offering Isaac.
One is left with the nagging feeling, “Have I been processed enough?”
Hebrews 11:8-19 New International Version (NIV)
8 By faith Abraham, when called to go to a place he would later receive as his inheritance, obeyed and went, even though he did not know where he was going. 9 By faith he made his home in the promised land like a stranger in a foreign country; he lived in tents, as did Isaac and Jacob, who were heirs with him of the same promise. 10 For he was looking forward to the city with foundations, whose architect and builder is God. 11 And by faith even Sarah, who was past childbearing age, was enabled to bear children because she[a] considered him faithful who had made the promise. 12 And so from this one man, and he as good as dead, came descendants as numerous as the stars in the sky and as countless as the sand on the seashore.
13 All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance, admitting that they were foreigners and strangers on earth. 14 People who say such things show that they are looking for a country of their own. 15 If they had been thinking of the country they had left, they would have had opportunity to return. 16 Instead, they were longing for a better country—a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared a city for them.
17 By faith Abraham, when God tested him, offered Isaac as a sacrifice. He who had embraced the promises was about to sacrifice his one and only son, 18 even though God had said to him, “It is through Isaac that your offspring will be reckoned.”[b] 19 Abraham reasoned that God could even raise the dead, and so in a manner of speaking he did receive Isaac back from death.
By faith Abel brought God a better offering than Cain did.
By faith he was commended as righteous, when God spoke well of his offerings.
And by faith Abel still speaks, even though he is dead.
