We read in Isaiah, “Behold, I am creating a new heaven and a new earth, and the earlier heaven and earth will not be remembered or overwhelm the heart. Behold, I am going to make Jerusalem a rejoicing and its people a joy” (Isaiah 65:17). In the Book of Revelation we read, “I saw a new heaven and a new earth, and I saw the holy Jerusalem coming down from God out of heaven, prepared like a bride for her husband. And the One sitting on the throne said, ‘Behold, I will make all things new’” (Revelation 21:1, 2, 5). A number of times we read that no one can come into heaven except the people who have been written in the Lamb’s book of life (Revelation 13:8; 17:8; 20:12, 15; 21:27). “Heaven” in these passages does not mean the visible heaven or sky that is before our eyes; it means the angelic heaven. “Jerusalem” does not mean some city from the sky; it means the church that will descend out of the angelic heaven from the Lord. Lamb’s book of life” does not mean a book written in heaven that will be opened; it means the Word, which is from the Lord and is about him.
In fact, the reason why Jehovah God, who is called “the Creator” and “the Father,” came down and took on a human manifestation was so that we could turn to him and form a partnership with him, a point I have supported, proven, and established with the previous statements in this chapter.
When we go to see someone, we do not go to the person’s soul. Who would be able to go to someone’s soul? No, we go to the actual person. We see the person eye to eye and talk with the person face to face. It is the same with God the Father and the Son because God the Father is present in the Son the way a soul is present in its body.
The following passages in the Word teach that we have to believe in the Lord God the Savior:
God so loved the world that he gave his only begotten Son so that everyone who believes in him would not perish but would have eternal life. (John 3:16)
Those who believe in the Son are not judged; but those who do not believe have already been judged because they have not believed in the name of the only begotten Son of God. (John 3:18)
Those who believe in the Son have eternal life. Those who do not believe in the Son will not see life; instead God’s anger will remain upon them. (John 3:36)
The bread of God is the One who comes down from heaven and gives life to the world. Those who come to me will never hunger and those who believe in me will never thirst. (John 6:33, 35)
This is the will of the One who sent me, that all who see the Son and believe in him should have eternal life, and I will revive them on the last day. (John 6:40)
They said to Jesus, “What shall we do to perform the works of God?” Jesus answered, “This is God’s work, to believe in the One whom the Father sent.” (John 6:28, 29)
Truly I say to you, those who believe in me have eternal life. (John 6:47)
Jesus cried out, saying, “If any are thirsty, they must come to me and drink. If any believe in me, rivers of living water will flow out of their bellies.” (John 7:37, 38)
Unless you have believed that I am [he], you will die in your sins. (John 8:24)
Jesus said, “I am the resurrection and the life. Those who believe in me, even if they die they will live. And everyone who lives and believes in me will never die.” (John 11:25, 26)
Jesus said, “I have come into the world as a light so that all who believe in me will not remain in darkness.” (John 12:46; 8:12)
As long as you have the light, believe in the light so that you may be children of the light. (John 12:36)
