“For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them.”
2 Peter 2:21 (ESV)
An idea stitched through Proverbs 15 is that the God of Heaven prefers human behavior that is good and has an aversion to human behavior that is bad (to put it mildly). The Maker of mankind pays attention to both the wicked and the righteous (Proverbs 15:3). God sees all that happens on earth and, although all bad is wrong from His perspective, there seems to be a certain kind of action that uniquely draws His ire: people, who "speak on behalf of God", using their influence to persuade others to evil–such people are called false prophets and false teachers (Jeremiah 23:16-17, 2 Peter 2:1). How do we avoid becoming like these people and live in a way that pleases our Maker?
Looking through the whole of scripture, one will discover that nearly all the people God employed for His purposes displayed humility (or were first humbled), while those whom God rejected or stopped using were dragged down by pride. When Jesus ministered in Judea and the surrounding regions, he embraced people who were stereotypically seen as bad (or, unrighteous) and opposed those who were known (and self-described) as good (or, righteous). While it is true that those whom Jesus befriended did bad things and those whom Jesus antagonized did good things, the defining distinction between the two was humility (in the former) and pride (in the latter).
The religious leaders of first-century Jerusalem saw themselves as righteous men who had things figured out–they needed no one to save them. The outcasts, meanwhile, longed for salvation–both from the Roman overlords and their own sinfulness. In other words, the people who embraced Jesus saw him as a doctor and themselves as the sick, while those who rejected him, saw Jesus as an instigator and themselves as the people preserving the peace. If one denies they have a problem, one cannot get the help needed.
There is a conundrum for the Christian: we are called to do good works (Ephesians 2:10) and to represent Christ on God's behalf (2 Corinthians 5:10), but we are also warned that one who has claimed to be a Christian (maybe even one who has been an effective evangelist) can come to a place where, because of their pride, it would have been better if they had "never known the way of righteousness" (2 Peter 2:21). How do we avoid this state, while being faithful to our calling?
From what I see from scripture, the best antidote to getting on God's bad side is to live in, with, and by humility. First, by fearing, above all (with reverence, awe, and worship) Yahweh. Second, by recognizing Jesus as the only way to the Father, to life eternal, and to the good life. Third, by recognizing that, while this knowledge radically changes lives, it doesn't make one superior to anyone else.
You can, with great fervor, study your Bible for countless hours every day, and do all the spiritual practices prescribed or implied by the text, but it won't make you any better off...unless you are aware and live as though you need a doctor and view Jesus as that doctor. The religious leaders of Jesus' day didn't recognize the great physician because they didn't acknowledge their sickness. If we want to make sure we don't go down that same dead-end road, if we don't want to get scolded or labeled as a false teacher, we must take our humble medicine every day.
