Mission within the Eternal Covenant (Isaiah 55:1–5)
Mission within the Eternal Covenant (Isaiah 55:1–5) 3/22/2026
We are living in a very difficult age. Since the fall of mankind in Genesis 3, endless disasters and wars have been prophesied in the Bible. Then how should God’s people live in such a time? The Bible records God’s absolute plan concerning the suffering that humanity faces. Therefore, in verses 1–2, those who are thirsty, hungry, and suffering are called to come to God and listen.Whether it is personal, family, church, or societal problems, God’s people must find God’s absolute plan in Scripture.
First, fallen humanity cannot solve its own problems, so we are told to hold on to Christ (Isaiah 7:14; 9:6; 53:5; 60:1–2).
This is our heavenly mandate. No matter what happens, we must hold on to Christ, because Christ is the power and wisdom of God (1 Corinthians 1:24).
Second, within this Christ, God has chosen and called those who will be used. They are called the remnant (Isaiah 6:13; 10:21–22).
This is our calling. When God calls us, it contains His absolute grace and love (Romans 11:5).
We are saved within this grace. Our suffering becomes an opportunity to deeply enjoy that grace. We are to live our whole lives enjoying it (1 Corinthians 15:10).
Third, through those who hold on to this absolute answer and absolute grace, God will save all nations (Isaiah 49:6; 60:1–5).
This is the mission of those who hold on to the absolute answer and grace. Even if we are small and lacking, if we hold on to God’s heavenly mandate, calling, and mission, God can do anything through us (Isaiah 60:21–22). God has given this absolute plan as a promise. That promise is called the covenant, and it is an eternal covenant (verse 3).
- Through those who hold this covenant, God has promised three blessings (4).
Do not struggle merely for success. A good university or a good job is not the issue. Become one who enjoys God’s blessings (a spiritual summit).
1) He will establish them as witnesses to all peoples.
This is also Christ’s final promise. He will raise us to be witnesses to the ends of the earth (Acts 1:8). No matter the situation, do not be shaken. The God of the throne has become our absolute bartizan (Isaiah 62:6–7). Our weaknesses, hardships, crises, tears, and suffering, all can be overcome when we hold on to this conclusion. This is not just any testimony. It is a testimony that can save all nations. There are people waiting to hear our testimony.
2) He will establish them as leaders of all peoples.
A leader is one who goes ahead. What do they do? They show the way (John 14:6), give the answer (John 19:30), and plant vision (Acts 2:17). We must not live at the level of unbelievers in the field. We must not go to missions and return having done meaningless things. We must accomplish this work.
3) He will establish them as commanders of all peoples.
People suffer disasters without knowing where it comes from. We must proclaim Christ to them and, through the authority of His name, break the power of darkness behind it (Mark 16:17–18). Those who know the mystery of Christ and pray to break darkness will change the flow even in places where they briefly stay.
- Why must God bless those who hold this covenant in this way?
Because saving all nations is God’s heart, plan, and ultimate conclusion (Isaiah 66:22).
Since people miss this, God sometimes allows His beloved people to enter problems.
1) This is why God allowed Israel to become slaves, captives, and subjects.
① In the age of slavery, who were called?
Joseph, sold as a slave, was recognized by his master and later by the king (Genesis 39:3; 41:39). Only later did he realize why God sent him to Egypt (Genesis 50:20). Moses, raised as a prince but becoming a murderer, fugitive, and powerless man, was called by God and sent to Pharaoh (Exodus 3:18). Through him, God broke Pharaoh and freed Israel from 400 years of slavery.
② In the age of captivity (Babylon and Persia), who were called?
Though elevated as governors and queens, they were envied and targeted by Satan. Daniel continued praying with thanksgiving even knowing he would be thrown into the lions’ den, and God saved him. Even the king acknowledged it (Daniel 6:26). Esther confessed, “If I perish, I perish,” fasted for three days, and stood before the king. Her enemies were completely defeated.
③ When Israel was under Roman rule, how did God use the Mark’s Upper Room church that had the conclusion of only Christ?
They held to the Word proclaimed through Peter, prayed, and broke bread, and the number of believers grew daily. Though persecution increased, God sent them to Antioch, beginning the first world missions. In the 18th century, God used England because its churches sent missionaries worldwide. In the 19th and 20th centuries, God used America for the same reason. In the 21st century, God is using Korea, once poor and war-torn, for this purpose.
Whether individuals, families, or nations—when aligned with God’s mission, they are used like this.
2) “A nation you do not know will call you” (5a).
① Those chosen by God receive grace of salvation, dedication, and signs of blessing. Through mission dedication worship, we realize God’s calling and mission and preview these blessings.
② This is why Paul saw the vision of Macedonia when crossing into Europe (Acts 16:9–10). In the field, we will meet prepared people from many nations – 237 nations and 5000 tribes.
Even in problems, if we think of God’s will and pray with His heart, we will experience these blessings.
3) “A nation that does not know you will run to you” (5b).
① “Run” in Hebrew implies coming with thirst, earnestness, and longing. The multi-ethnic disciples we met at our church came with this kind of longing. When we share why only Christ is the answer, their lives become testimonies, and God raises them up.
② God has been doing this and will continue until the day the Lord returns.
All the disasters and wars today are signs that the end is near. The end will come after the gospel is preached to all nations (Matthew 24:14). Those used for this are the absolute disciples.
Conclusion – This is possible because God has already glorified us at the moment of our salvation. All who have received Christ already possess His life, light, authority, and glory (Isaiah 60:1–2). May today’s mission dedication worship be a time for both individuals and the church to deeply restore all the blessings God has prepared.
