The inspiration for Angel Wings is Psalms 91.
Proverbs 8:1-36
Excerpt
8 All the words of my mouth are with righteousness; Nothing crooked or perverse is in them.
12 “I, wisdom, dwell with prudence, And find out knowledge and discretion. 14 Counsel is mine, and sound wisdom; I am understanding, I have strength. 23 I have been established from everlasting, From the beginning, before there was ever an earth. 30 Then I was beside Him as a master craftsman; And I was daily His delight, Rejoicing always before Him, 35 For whoever finds me finds life, And obtains favor from the Lord; Gold symbolizes wisdom, present before the beginning of creation; blue represents the heavens from which it flows. Purple signifies the honor and favor that come with possessing such wisdom."
Psalms 22:27-31 (NKJV)
Wisdom comes from the Lord, before the foundations of the world is even established.
Wisdom is represented by the gold streak across the cosmos flag.
