ScriptureS used in this teaching:

Isaiah 28: 23-29

Give ear, and hear my voice;
    give attention, and hear my speech.
Does he who ploughs for sowing plough continually?
    Does he continually open and harrow his ground?
When he has levelled its surface,
    does he not scatter dill, sow cumin,
and put in wheat in rows
    and barley in its proper place,
    and emmer as the border?
For he is rightly instructed;
    his God teaches him.
Dill is not threshed with a threshing sledge,
    nor is a cart wheel rolled over cumin,
but dill is beaten out with a stick,
    and cumin with a rod.
Does one crush grain for bread?
    No, he does not thresh it for ever;
when he drives his cart wheel over it
    with his horses, he does not crush it.
This also comes from the Lord of hosts;
    he is wonderful in counsel
    and excellent in wisdom.

Hebrews 12: 4-11

In your struggle against sin you have not yet resisted to the point of shedding your blood.
And have you forgotten the exhortation that addresses you as sons?
“My son, do not regard lightly the discipline of the Lord,
    nor be weary when reproved by him.
For the Lord disciplines the one he loves,
    and chastises every son whom he receives.”
It is for discipline that you have to endure.
God is treating you as sons. For what son is there whom his father does not discipline? you are left without discipline, in which all have participated, then you are illegitimate children and not sons.
Besides this, we have had earthly fathers who disciplined us and we respected them.
Shall we not much more be subject to the Father of spirits and live? they disciplined us for a short time as it seemed best to them, but he disciplines us for our good, that we may share his holiness.
For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it.

2 Timothy 3:16-17
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work.

Hebrews 3:12-14
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God.
But exhort one another every day, as long as it is called “today”, that none of you may be hardened by the deceitfulness of sin.
For we have come to share in Christ, if indeed we hold our original confidence firm to the end.

Titus 2:11-14
For the grace of God has appeared, bringing salvation for all people, training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, waiting for our blessed hope, the appearing of the glory of our great God and Saviour Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works.

Psalm 131
O Lord, my heart is not lifted up;
    my eyes are not raised too high;
I do not occupy myself with things
    too great and too marvellous for me.
But I have calmed and quietened my soul,
    like a weaned child with its mother;
    like a weaned child is my soul within me.
O Israel, hope in the Lord
    from this time forth and for evermore.
