@Sirona , Proverbs 4:18 refers to Biblical understanding getting brighter, ie., clearer, ie., more refined.
Contrary to what some claim, it’s not behaviour that Proverbs 4:18 is addressing — Christians have
always known God’s standards of behavior...sex outside of marriage, lying and thievery are still improper, concern & love for others is still acceptable. Rather, it’s the teachings from Scripture, what they mean, that would become “brighter”.
This being the case, in line w/ this passage, we should expect a religion using the Bible as it’s guide, to adjust its understanding from time to time.
Otherwise, how could their path
ever get brighter?
Jesus’ words @ Luke 10:21 are appropriate here: it’s his
Father, (ie., the God of ancient Israel, Yahweh / Jehovah) who gives revelation, not Jesus himself. He also hides it from some, according to that verse. It would stand to reason, that God would hide His truth from those who disobey His requirements....those who are greedy, selfish, or are sexually promiscuous. How much of the religious world tacitly condone such actions? What about joining conflicts & killing their brothers, due to some geographical borders?
Titus 1:16. John 13:34-35.
Do you think God would reveal truth to these?
Hope you stay well, my cousin.
Sorry, but read the context of Proverbs, especially the first few chapters. It isn't addressed to Christians because they weren't around at the time, even though it applies to them now, but it addresses young people and guides them on the right way to walk. That is why those chapters constantly contrast the behaviour of the good vs the behaviour of the wicked and who you should follow. Nothing doctrinal in there. It definitely isn't talking about Bible understanding regarding doctrine.
Also, since the context doesn't address Christians but Israelites of the time, and we know how the Israelites struggled between behaving properly and not, especially as pointed out in the book of Judges and the prophets, it makes perfect sense that the book about wisdom would be teaching readers how to behave.
If you want to argue the point, explain the context of the whole of chapter 4 and how it specifies doctrine and not behaviour.
Just to help you along, here is the whole of Proverbs 4. Understandably, since chapters and verses were inserted later, all the chapters before this and after should be read as well. Where does it talk about doctrine? Notice how often it talks about "walking the right paths" and not "believe the right thing". All the verse I bold in red refer to behaviour.
4 Listen, my sons, to a father’s instruction;
pay attention and gain understanding.
2 I give you sound learning,
so do not forsake my teaching.
3 For I too was a son to my father,
still tender, and cherished by my mother.
4 Then he taught me, and he said to me,
“Take hold of my words with all your heart;
keep my commands, and you will live.
5 Get wisdom, get understanding;
do not forget my words or turn away from them.
6 Do not forsake wisdom, and she will protect you;
love her, and she will watch over you.
7 The beginning of wisdom is this: Get wisdom.
Though it cost all you have, get understanding.
8 Cherish her, and she will exalt you;
embrace her, and she will honor you.
9 She will give you a garland to grace your head
and present you with a glorious crown.”
10 Listen, my son, accept what I say,
and the years of your life will be many.
11 I instruct you in the way of wisdom
and lead you along straight paths.
12 When you walk, your steps will not be hampered;
when you run, you will not stumble.
13 Hold on to instruction, do not let it go;
guard it well, for it is your life.
14 Do not set foot on the path of the wicked
or walk in the way of evildoers.
15 Avoid it, do not travel on it;
turn from it and go on your way.
16 For they cannot rest until they do evil;
they are robbed of sleep till they make someone stumble.
17 They eat the bread of wickedness
and drink the wine of violence.
18 The path of the righteous is like the morning sun,
shining ever brighter till the full light of day.
19 But the way of the wicked is like deep darkness;
they do not know what makes them stumble.
20 My son, pay attention to what I say;
turn your ear to my words.
21 Do not let them out of your sight,
keep them within your heart;
22 for they are life to those who find them
and health to one’s whole body.
23 Above all else, guard your heart,
for everything you do flows from it.
24 Keep your mouth free of perversity;
keep corrupt talk far from your lips.
25 Let your eyes look straight ahead;
fix your gaze directly before you.
26 Give careful thought to the paths for your feet
and be steadfast in all your ways.
27 Do not turn to the right or the left;
keep your foot from evil.
