It's you legalists who have failed miserably.
The mysteryboy tried to distort Acts 16 into a pretzel.
Salvation is by grace through faith, not passing a written exam on "the sin debt issue according to MADists".
That's rich; the Jerry Shugart legalist hurling that at others.
You are a coward. You have to know a lost man must know that "the wages of sin is death.. but God commended His love toward us in that while we were yet sinners, Christ died for us" Rom. 6:23; 5:8.
If you don't you are lost.
If you do not point that out to a lost man for him to either reject or place his faith in, he will remain lost.
