Glory is about recognizing and attributing worth to the person to whom it is due. It's about who gets the credit. Does it matter? Yes!
If a person does not receive recognition for the glory that is due, then that person is undervalued by the people who should recognize his or her worth. His relevance to their lives is hidden. If a person is credited with glory for work someone else accomplished, then the glory is misdirected. If a person takes credit for the work of someone else, then the person who received the recognition is discredited and justly regarded as disingenuous.
Glory is rooted in the recognition of the character and works of the person whose qualities and work is being reviewed. So, proper attribution of glory requires that the identity and accomplishments of a person be properly known.
Glory is about giving credit where credit is due.
“Give unto the LORD the glory due unto his name; worship the LORD in the beauty of holiness.” — Psalm 29:2
Satan's ambition is to take and diminish the glory of God through lies and deception and receive that glory himself. Since Adam's disobedience, we have all been following Satan's lead.
Missions is about leading people to know and believe the truth about God's person, His glory, leading to reflecting His worth. Missions, global ministry, is about recognizing and proclaiming the value and worth of our Creator in the context of the reality of who He is and what He has done.
I am the LORD: that is my name: and my glory will I not give to another, neither my praise to graven images. — Isaiah 42:8
