Jesus came to earth 2,000 years ago — so why does He need to come back again?
Couldn’t He have done everything during His first coming? If God is all-powerful, why not complete His plan all at once?
These are great questions — and as we study the book of Revelation, it’s important to understand why Jesus’ second coming is essential to God’s plan.
The short answer:
Because this is how God designed it from the very beginning.
1. The Story of God’s Plan — From Creation to Covenant
The Bible tells the story of God’s relationship with humanity, beginning with His creation of the world and continuing through His covenant with the Jewish people.
Genesis 1:1–5
1 In the beginning God created the heavens and the earth.
2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, “Let there be light,” and there was light.
4 God saw that the light was good, and He separated the light from the darkness.
5 God called the light “day,” and the darkness He called “night.”
God created man in His image, but humanity turned away from Him through sin. The wickedness of mankind became so great that God sent a flood, saving only Noah and his family.
2. God’s Covenant With Noah
After the flood, God made a promise — a covenant — with Noah and all living creatures.
Genesis 9:8–16 (abridged)
“Never again will all life be destroyed by the waters of a flood… I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth.”
Though God promised never to destroy the earth by flood again, the problem of sin still remained. Humanity continued to rebel and live apart from God’s will.
3. God’s Covenant With Abraham and Israel
To address humanity’s sin, God began a new plan — one that would unfold through the nation of Israel.
He chose Abraham, and through his descendants — Isaac and Jacob (Israel) — God formed the Jewish people.
He gave them His law, including the Ten Commandments, and entered into a covenant relationship with them.
This first covenant, however, was limited to Israel. The rest of the world (the Gentiles) was not yet included.
4. God’s Promise Extends to the Nations
Centuries later, through the prophet Isaiah, God revealed that His plan would not stop with Israel alone:
Isaiah 49:6
“It is too small a thing for you to be my servant to restore the tribes of Jacob… I will also make you a light for the Gentiles, that my salvation may reach to the ends of the earth.”
This prophecy pointed to the coming Messiah — Jesus Christ — who would bring salvation not only to Israel but to all nations.
5. Jesus’ First Coming — The New Covenant
When Jesus came to earth the first time, His mission was first to fulfill God’s promises to Israel.
Yet, through His death and resurrection, He opened the door of salvation to all people — both Jews and Gentiles.
Jesus established a New Covenant, one not based on law, but on grace.
Romans 8:1–2
“Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death.”
This New Covenant offers forgiveness and eternal life to everyone who believes in Him.
6. The Great Commission — The Time Between the Comings
Before ascending to heaven, Jesus gave His followers a mission:
Matthew 28:18–20
“All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
Jesus’ first coming brought salvation. His ascension began a period of grace, allowing time for both Jews and Gentiles to receive the gift of eternal life.
7. Why Jesus Must Come Again
Jesus’ second coming will complete what He began.
The first coming was about salvation — the second will be about restoration and judgment.
He will return not as the suffering servant, but as the Lion of Judah, to redeem all creation and establish His eternal kingdom.
As believers, we are grateful that God has given us time to turn to Him and become part of His covenant through Christ.
8. Looking Forward — The Book of Revelation
The book of Revelation gives us a glimpse of what Jesus’ return will look like — and a reminder to be ready.
His second coming is not a delay, but part of God’s perfect plan to bring salvation to the whole world.
Final Thoughts
Jesus came once to save us.
He will come again to reign over us.
And for those who believe, His return is not something to fear — but something to look forward to with hope and joy.
“He who testifies to these things says, ‘Yes, I am coming soon.’
Amen. Come, Lord Jesus.” — Revelation 22:20
