John 1:51
Then Jesus said to him, "Truly, truly, I tell you, you will see heaven opened up and the angels of God going up [from] and coming down on the Son of man" [i.e., probably a reference to angels ministering to Jesus' needs. See Matt. 4:6, 11; Luke 22:43].
2 Corinthians 3:18
But all of us [Christians], with unveiled faces, see the Lord's splendor reflected, as [though we were] looking in a mirror, and [so] are being transformed into His likeness in ever-increasing splendor. This is [the work] of the Lord, [who is] the Holy Spirit.
Ephesians 3:10
This was done so that now God's many-sided wisdom could be made known through the church, to the rulers and authorities in the heavenly realms [Note: "Heavenly realms" here refers to the world around us, where these angelic beings (good or bad) view the unfolding of God's wonderful plan],
Philippians 3:8
What is more, I consider everything to be a loss compared to the surpassing value of knowing Christ Jesus [as] my Lord, for whose sake I have suffered the loss of all things. [I now] consider [all of] them to be trash, in order to gain Christ
1 Timothy 3:16
And without question the revealed secret of godly living is great. [It is this]: He [i.e., Christ, or God], who appeared in a fleshly body [was] vindicated [of false charges] by the Holy Spirit; [He was] seen by angels, was preached among the nations, was believed in throughout the world [and finally] was taken up into glory [i.e., heaven].
Hebrews 1:14
Are not all angels ministering spirits sent out [by God] to serve those people who will inherit salvation?
1 Peter 1:12
It was revealed to these prophets that you people, not they, were the ones being ministered to in the matters now being announced to you by those who preached the Gospel to you by the Holy Spirit, who was sent from heaven. [This message contained] things which angels would like to look into.
