In the sixth month of Elizabeth’s pregnancy, God sent the angel Gabriel to Nazareth, a town in Galilee, to a virgin pledged to be married to a man named Joseph, a descendant of David. The virgin’s name was Mary.
Luke 1:26-27 (NIV)
Gabriel was usually met with fear, and he had to begin his conversations with words of comfort and cheer for Daniel, Zechariah, and Mary. It is possible that Gabriel was also the angel that appeared to Joseph in Matthew 1:20, but this is not certain, since that angel is unnamed in Scripture. What we do know is that Gabriel is one of God’s good and holy angels. He has a favored position as an angel who “stands in the presence of God” (Luke 1:19), and he was selected to deliver important messages of God’s particular love and favor to chosen individuals.
The Angel Gabriel is considered the most important of all the angels in Islam. In the Quran, the angel is called Jibreel or the Holy Spirit. The Angel Jibreel’s main responsibility is to communicate the Words of Allah to His prophets.
