Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us. 2Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God. 3Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart.

4In your struggle against sin, you have not yet resisted to the point of shedding your blood. 5And you have forgotten that word of encouragement that addresses you as sons:
“My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
6because the Lord disciplines those he loves,
and he punishes everyone he accepts as a son.”

7Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? 8If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. 9Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits and live! 10Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness. 11No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.

12Therefore, strengthen your feeble arms and weak knees. 13“Make level paths for your feet,” so that the lame may not be disabled, but rather healed.”  (Hebr 12:1-13 niv)

We are surrounded by a great cloud of witnesses who lived & taught the truths of Scripture. Sometimes they’re referred to as saints.

False doctrine is sin that easily entangles. It hinders. It holds back. It afflicts the body of Christ as does cancer.

We fix our eyes on Jesus through the words of Scripture, against all opposition that wishes to take our eyes off our Lord and divert our focus.

Christ too endured the opposition of sinful men, which is a comfort for us when the cross presses down on us hard. He warns it will be no different for us if we are faithful — even to the point of splitting families. Struggling against false teaching and confessing the truth is a form of discipline. It drives you into the Word & makes you cling to the truth. The harvest of righteousness and peace comes later. If we can endure divisions even within our own families & households for the sake of the gospel, we will win an everlasting reward.
