The question is not that the Milkman did these things...but they he did not know he did these things.
For once we know, it becomes the sin.
Yet, it is still the sin for those who never knew, but it becomes different once we are open to grace and refuse Him.
Milkman did not know...but because the Lord called Him with grace, he now knows.
BUT if a man refuses that grace, that man then blasphemes.
Hope this clarifies...
BECAUSE if we were to condemn the unbelievers who never knew, and never had grace...then how could they acquire grace...yet we know they do.
Scripture tells us to patiently teach, because later the unbeliever may repent.
And if the non believer never repents, it matters not that he never believed, but he refused grace and remained an unbeliever.
Hey...did this make sense?
