Angels are mentioned nearly 300 times in the Bible. They were created by God to serve Him and act as His messengers and agents. Paul writes in Colossians 1:16, "[F]or through [Jesus] God created everything in the heavenly realms and on earth. He made the things we can see and the things we can’t see—such as thrones, kingdoms, rulers, and authorities in the unseen world. Everything was created through him and for him." Angels carry out various assignments for God, including worshiping God (Revelation 4:8), protecting and ministering to God's people (Hebrews 1:14), performing the will of God (Psalm 104:4), and acting as God's messengers (Genesis 22:11-12, Acts 8:26, Acts 27:23). In the book of Luke, we see Gabriel bringing the message of God to both Zechariah and Mary. He also had authority from God to speak judgment against Zechariah (Luke 1:19-20) and blessing upon Mary (Luke 1:28).
