Let us throw off everything that hinders and the sin that so easily entangles (v.1)
To endure discipline, we have to throw off everything that hinders. This means that we have to get rid of things that we already know that causes us to stumble. Getting rid means stopping if we are sinning.

It may also mean repentance and submission to authorities. After all, the purpose of discipline is restoration and not condemnation. Getting rid of these may not be easy, and we may even think of compromising what we believe so that we may not suffer. But truths in the Bible will always remain as truths.
