Rom 9:11
for though
the twins were not yet born and had not done anything good or bad, so that God's purpose according to
His choice would stand,
not because of works but because of Him who calls,
Ephesians 2:8-9
For by grace you have been saved through faith; and this
salvation is not of yourselves,
it is the gift of God;
not a result of works, so that no one may boast.
Heb 6:1
Therefore leaving the elementary teaching about the Christ, let us press on to maturity, not laying again a foundation of
repentance from dead works and of faith toward God,
It is certainly true that prior to our salvation, all our "works" of righteousness are as filthy rages to God. However, after individuals are born anew, becoming a new creation created for good works, to say good words indicates a changed life does not seem out of line. To say we are not to strive to become more Christ-like also seems odd.
To claim "Lordship" salvation says good works are necessary for salvation is false. The idea is our total "all in" commitment to Christ includes our commitment to make Christ the lord of our life, a commitment to follow His commands and serve Him as best be can. We all know the "death bed" conversion story where someone died before they ever did much in the way of good works, yet their salvation was secure. Think about the thief on the cross.
Bottom line, good works in our eyes does not proof salvation, but serving Christ faithfully following salvation provides assurance of salvation, just as the lack thereof provides assurance of non-salvation.
