Consider him who endured from sinners such hostility against himself,
so that you may not grow weary or fainthearted.
How do we get the power to keep following Jesus, when following Jesus is difficult? This difficulty can involve being sinned against, and not retaliating. This difficulty can be living in an environment where you are the only Christian in the household, and you are looked down on. This difficulty can be simply seeking to live faithfully in the midst of a culture that has a growing contempt for Jesus and Christians.
Hebrews gives us a way. The author tells us to consider Jesus and what and how he endured to ransom us back to God. What this can look like is, if you are mocked for following Jesus, look for places in the gospel for how Jesus was mocked. How did he respond? What was it like for Jesus who never sinned and was never foolish to endure mocking? Seek to experience awe for the fact that Jesus endured this mocking as a way of suffering for us, as a way of suffering with us. Considering Jesus in this way, helps us to see that Jesus identifies with us in our suffering. He is with us and he did it for us.
“He did this for me,” shows me how much I am loved, and love casts our fear. “He did this with me,” shows me he can give me the strength to live as he has lived.
This is proactive preparation for enduring difficulty throughout the day. When in the midst of difficulty, look at the gospels in the Bible to see places where Jesus endured what you are needing to endure and consider Jesus. Seek your strength and courage from him.
