Colossians 2:23 KJV
 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh. Will-worship—arbitrarily invented worship: would-be worship, devised by man's own will, not God's. So jealous is God of human will-worship, that He struck Nadab and Abihu dead for burning strange incense (Le 10:1-3). So Uzziah was stricken with leprosy for usurping the office of priest (2Ch 26:16-21).
Compare the will-worship of Saul (1Sa 13:8-14) for which he was doomed to lose his throne. This "voluntary worship" is the counterpart to their "voluntary humility" (Col 2:18): both specious in appearance, the former seeming in religion to do even more than God requires (as in the dogmas of the Roman and Greek churches); but really setting aside God's will for man's own; the latter seemingly self-abasing, but really proud of man's self-willed "humility" (Greek, "lowliness of mind"), while virtually rejecting the dignity of direct communion with Christ, the Head; by worshipping of angels.

“Much more is worship of man’s devising distasteful to the all-wise God, who sees through all colours, and though he loves a willing worshipper, yet he hates will-worship.” Matthew Poole
Immortal, invisible, God only wise, in light inaccessible hid from our eyes, most blessed, most glorious, the Ancient of Days, almighty, victorious, thy great name we praise.
Unresting, unhasting, and silent as light, nor wanting, nor wasting, thou rulest in might; thy justice like mountains high soaring above thy clouds, which are fountains of goodness and love.
To all life thou givest, to both great and small; in all life thou livest, the true life of all; we blossom and flourish as leaves on the tree, and wither and perish but naught changeth thee.
Great Father of glory, pure Father of light, thine angels adore thee, all veiling their sight; all praise we would render, O help us to see 'tis only the splendor of light hideth thee.
