Jesus is God. He is the Son of God and is one with God the Father.
They are three-in-one with God the Holy Spirit. The Son was with the Father in the beginning and is God. Jesus is eternal and is not a created being. God the Father, God the Son, and God the Holy Spirit are one and are eternal. They existed always and will exist forever.
God the Father wants everyone on earth to be in right relationship with Him. But their disobedience to Him and His laws separated them. God the Father sent Jesus, God the Son, to earth to be born as a baby. God the Holy Spirit came upon Mary and she gave birth to baby Jesus. Jesus grew, lived a sinless life, obeyed the will of God the Father, gave His life as a sacrifice on the cross, and rose from the death in victory over sin and death.
Jesus rules and reigns in heaven. All authority in heaven and on earth has been given to Him. He intercedes for us before God the Father. One day, Jesus will return to earth in glory and power and fulfill the will of God the Father in the end times of world history.
To receive a better understand of Jesus, please read John 1:1-14 in the New Testament portion of the Bible. You will read that Jesus was with God and was God. John provided names for Jesus such as Word, life, and light. John ended this portion of Scripture with what Jesus did: “The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth” (John 1:!4, NIV).
