18 With every prayer and request, pray at all times in the Spirit, and with this in view, be alert with all perseverance and every request for all the saints,
19 and pray in my behalf, that speech may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel,
20 for which I am an ambassador in chains; that in proclaiming it I may speak boldly, as I ought to speak.
Ephesians 6:18-20
The word “mystery” means beyond human knowledge or understanding. God’s mysteries baffle the unbelieving, but bless the believer. The mystery of righteousness, like some of the other great mysteries of God, we cannot comprehend, but we know it works. We stand amazed at this great mystery which enables God to change the human heart, its attitudes, its desires, and its nature.
God, a holy God, who loves righteousness and hates wickedness, through a process of redemption has refashioned us in the image of Himself. How marvelous! For generations He has been applying His righteousness to the hearts of men. Even in our time, with its complexities of living, God is in the business of changing men and women by the mystery of righteousness.
