IMHO, the article goes much further to confuse believers who have fallen into religiousity and legalism into mistaken and confused notions. Rather than clarify the meanings of belief, faith, trustworthiness, doctrine, sanctification, life after salvation, and non-meritorious thinking, the article tends to encourage morality and now condoning any good in any environment as identifiable with God.
It might be noted that in every instance of Satan's falls in the Scripture, he was always promoting good and surrounded by perfect environment, yet in each case he failed to exhibit the mind of Christ and remain obedient to God by God's methods.
Do you mind giving me some Chapter and Verse references?
