These are beliefs held by the Jehovah’s Witnesses, as stated on their website
We come from hundreds of ethnic and language backgrounds, yet we are united by common goals. Above all, we want to honor Jehovah, the God of the Bible and the Creator of all things. We do our best to imitate Jesus Christ and are proud to be called Christians. Each of us regularly spends time helping people learn about the Bible and God’s Kingdom. Because we witness, or talk, about Jehovah God and his Kingdom, we are known as Jehovah’s Witnesses.
Who is Jesus?
God does not have a literal wife with whom he fathered children. But he is the Creator of all life. (Revelation 4:11) Therefore, the first human that God created, Adam, is called a “son of God.” (Luke 3:38) Similarly, the Bible teaches that Jesus was created by God. So Jesus is also called a “Son of God.”—John 1:49.
Jesus is the King of God’s Kingdom in heaven. He began ruling in 1914.—Revelation 11:15.
At times, individuals are known by more than one name. For example, the patriarch Jacob is also known as Israel, and the apostle Peter, as Simon. (Genesis 49:1, 2; Matthew 10:2) Likewise, the Bible indicates that Michael is another name for Jesus Christ, before and after his life on earth. Let us consider Scriptural reasons for drawing that conclusion.
God’s Word refers to Michael “the archangel.” (Jude 9) This term means “chief angel.” Notice that Michael is called the archangel. This suggests that there is only one such angel. In fact, the term “archangel” occurs in the Bible only in the singular, never in the plural. Moreover, Jesus is linked with the office of archangel. Regarding the resurrected Lord Jesus Christ, 1 Thessalonians 4:16 states: “The Lord himself will descend from heaven with a commanding call, with an archangel’s voice.” Thus the voice of Jesus is described as being that of an archangel. This scripture therefore suggests that Jesus himself is the archangel Michael.
What about the Trinity?
However, we have learned from the Bible that Jesus is not Almighty God and that there is no Scriptural basis for the Trinity doctrine.—John 14:28. https://www.jw.org/en/jehovahs-witnesses/faq/jehovah-witness-beliefs/
How are we saved?
Deliverance from sin and death is possible through the ransom sacrifice of Jesus. (Matthew 20:28; Acts 4:12) To benefit from that sacrifice, people must not only exercise faith in Jesus but also change their course of life and get baptized. (Matthew 28:19, 20; John 3:16; Acts 3:19, 20) https://www.jw.org/en/jehovahs-witnesses/faq/jehovah-witness-beliefs/
Jehovah God, Jesus Christ, and the faithful angels reside in the spirit realm. * (Psalm 103:19-21; Acts 7:55) A relatively small number of people—144,000—will be resurrected to life in heaven to rule with Jesus in the Kingdom.—Daniel 7:27;2 Timothy 2:12; Revelation 5:9, 10; 14:1, 3.
God created the earth to be mankind’s eternal home. (Psalm 104:5; 115:16;Ecclesiastes 1:4) God will bless obedient people with perfect health and everlasting life in an earthly paradise.—Psalm 37:11,34. https://www.jw.org/en/jehovahs-witnesses/faq/jehovah-witness-beliefs/
Can you lose your salvation?
Yes. Just as a person saved from drowning could fall or jump back into the water, a person who has been saved from sin but fails to keep exercising faith could lose out on salvation. https://www.jw.org/en/bible-teachings/questions/what-is-salvation/
