1Tim 3:14-16, 16 And without controversy great is the mystery of godliness: God was manifested in the flesh, Justified in the Spirit, Seen by angels, Preached among the Gentiles, Believed on in the world
Pillar number 3. Seen by angels. The angels from above testified of His deity and ministered to Him knowing their role. Heb 2:9 “But we see Jesus, who was made a little lower than the angels, for the suffering of death crowned with glory and honor, that He, by the grace of God, might taste death for everyone.” Jesus in His weak times as a man fulfilling His mission was ministered to by the angels after being tempted of Satan in the wilderness and at the garden of Gethsemane in agony.
To add, He was seen by angels who confirmed to the women at the tomb that He was risen as He testified. Angels confirmed resurrection that validates the gospel, 1Cor 15:14 “And if Christ is not risen, then our preaching is empty and your faith is also empty”
