Jesus Christ is the Son of God. He was the Creator, He is our Savior, and He will be our Judge.
Under the direction of Heavenly Father, Jesus Christ created the earth (John 1:10, Hebrews 1:2).
When Jesus lived on the earth (approximately 2,000 years ago), He led a perfect life. He taught by word and example how people should live in love of God and others.
Through His suffering in the Garden of Gethsemane and by giving His life on the cross—that is, by performing the Atonement—Jesus Christ saved all of us from our sins as we follow Him. Because of the Atonement, we can be forgiven of our sins when we sincerely repent.
Through His Resurrection, Jesus Christ saved us from death. Because He overcame death, we will all be given the gift of resurrection (Acts 24:15, 1 Corinthians 15:22).
When life on this earth is over, Jesus Christ will be our Judge (Acts 10:42, Acts 17:31).
Now answer the question. Is Jesus the spirit brother of Satan?
From an Islamic website....
Mary — A Righteous Servant of God
The Holy Quran affirms the virgin birth of Jesus, repudiates the notion that Mary was not pious and that her birth was illegitimate. The Quran narrates Mary’s statement to an angel: “How can I have a child when no man has touched me and neither have I been unchaste?” (19:21)
Moreover, it is on account of her piety Chapter 19 in the Quran is named after her, and all pious Muslims are likened to her.
A Very Rare Phenomenon
The virgin birth of Jesus was a miracle, no doubt. But according to the Ahmadiyya Muslim view, miracles always work in accordance with God’s laws, no matter how limited our understanding of those laws are. Modern science has only just begun to study this rare phenomenon.
The Miracles of Jesus in the Holy Quran
The Holy Quran narrates several miracles of Jesus, including his ability to create birds, to cure ailments including blindness and raise the dead to life (Quran 3:50).
Ahmadi Muslims interpret these particular signs metaphorically. The people who accepted Jesus soared high like birds into the spiritual firmament above worldly, base concerns. Similarly in the metaphoric sense, he restored sight to the spiritually blind and life to the spiritually dead.
Jesus himself called the enemies of his day “blind” because of their hypocritical nature in matters of faith (Matthew 23:26). The very nature of his words about healing convey a spiritual change, not physical. It should also be remembered that Jesus spoke in parables, such as the famous line, “let the dead bury their dead” (Matthew 8:22).
The Holy Quran also describes disbelievers as deaf, dumb and blind (Quran 2:19) and the Holy Prophet (SAW) offered them ‘life’ and revival from such death (Quran 8:25).
Convinced of His Innocence
It is notable in the New Testament testimony that Pontius Pilate believed Jesus to be innocent and did not want him executed. One of the influences was a dream Pilate’s wife convincing her of Jesus’ innocence, and the message she passed on to Pilate was “leave that innocent man alone” (Matthew 27:19).
Pilate eventually acquiesced to the demand of the Jews that Jesus be crucified, as a riot was developing. However he then asked for a bowl of water and washed his hands before the crowd and exclaimed “I am innocent of the blood of this man. The responsibility is yours!” (Matthew 27:24)
