Colossians 1:24 Now I rejoice in my sufferings for your sake, and in my flesh I am filling up what is lacking in Christ’s afflictions for the sake of his body, that is, the church, of which I became a minister according to the stewardship from God that was given to me for you, to make the word of God fully known, the mystery hidden for ages and generations but now revealed to his saints. To them God chose to make known how great among the Gentiles are the riches of the glory of this mystery, which is Christ in you, the hope of glory. Him we proclaim, warning everyone and teaching everyone with all wisdom, that we may present everyone mature in Christ. For this I toil, struggling with all his energy that he powerfully works within me.
1 Corinthians 2:7 But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory.
Ephesians 3:3-10 how the mystery was made known to me by revelation, as I have written briefly. When you read this, you can perceive my insight into the mystery of Christ, which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.
Jeremiah 6:10 To whom shall I speak and give warning, that they may hear? Behold, their ears are uncircumcised, they cannot listen; behold, the word of the LORD is to them an object of scorn; they take no pleasure in it.
Jeremiah 3:15 “‘And I will give you shepherds after my own heart, who will feed you with knowledge and understanding.
1 Corinthians 2:6 Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away.
In the Biblical sense, a mystery is not a riddle. It is a truth that can only be known by revelation and not by intuition. Now it can be known because it now has been revealed to His saints. There are aspects to God’s plan that were not clearly revealed until Jesus Christ. The mystery of salvation for all who would believe and trust in and rely on Jesus Christ. The mystery of God’s grace, mercy, and love reaching out to all mankind. The mystery of the new birth and indwelling of the Holy Spirit. The mystery of hope, joy, peace, courage, love, gentleness, kindness, patience, in all things at all times through the power of the Holy Spirit. Our hearts ought to overflow with thankfulness and our lives are lived in such a way that in all things Jesus Christ is honored and glorified.
