When Matthew was describing Jesus, he quoted from Isaiah 42, saying this was a clear prophecy of and reference to Jesus:

Matthew 12:21 In his name the nations will put their hope. (Isaiah 42:4)

Jesus is our Hope. We know what He did for us through His life and death and resurrection. We should not expect the world around us to understand what we have.  Paul was God’s chosen messenger in the early church to take the message of Jesus to the Gentiles, the non-Jews. Paul knew the world would have a hard time understanding our hope as believers. At one of his trials, when he was on his way to Rome, he was appealing to a King who understood Jewish teachings and this is what he said.

Acts 26:6-7 And now it is because of my hope in what God has promised our fathers that I am on trial today. This is the promise our twelve tribes are hoping to see fulfilled as they earnestly serve God day and night. O king, it is because of this hope that the Jews are accusing me.

Those who have not been led by the Holy Spirit to know and believe in Jesus will not understand the hope that we have in Him. But that does not negate our hope. It is real because Jesus earned it for us.

Paul wrote about this a lot, especially throughout his letter to the believers in Rome.

Romans 4:18 Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, “So shall your offspring be.”

Romans 5:1 Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in the hope of the glory of God. Not only so, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out his love into our hearts by the Holy Spirit, whom he has given us.

Romans 12:12 Be joyful in hope, patient in affliction, faithful in prayer.

Romans 15:4 For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope.

Hope is ours in Christ. While the world around may not understand it – yet – if we keep living in that hope and speaking of the hope that is our in Christ, the Holy Spirit will work through us to lead others to know and believe in Jesus as well.
