Proverbs 1:22-23 English Standard Version (ESV)
22 “How long, O simple ones, will you love being simple?
How long will scoffers delight in their scoffing
and fools hate knowledge?
23 If you turn at my reproof,
behold, I will pour out my spirit to you;
I will make my words known to you.
The Good News is simple. God made it simple in order to make it easy to be saved. Now answer this question; would you want a baby to remain a baby forever? Part of us adorn the simplicity of infancy where love abounds, needs are simple, and messes are easy to clean up.
There is no hope of a future for that infant. Parents have hopes for a future and so does God.
What is reproof here? It is correction. An infant that walks and runs will explore a world that if fraught with danger. Reproof might sound like “Stop”, “Don’t touch that.” Seldom is it a simple no. Instruction in right behavior is never accomplish with constant comments of no. What must accompany reproof is guidance in the right way.
If we ignore God’s reproof will He deny us His Holy Spirit? No, but if you keep ignoring His reproof then something stronger than correction will be required.
On the spiritual side of this life lesson is a plea. Hear the Holy Spirit. If you have no sense of what the Holy Spirit does in your life, the tendency is to make mistakes and suffer consequences. God gave us of His Spirit to avoid consequences.
An infant can see mother and father and knows where that voice of correction is coming from. Hearing the Holy Spirit is a little more difficult.
John 3:8 English Standard Version (ESV) The windblows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.
Here is a hint. Even if you cannot hear the wind, you can feel it.
2 Timothy 3:16 underscores what you said about reproof and correction. Good word.
