"Lo! a secret to you am I telling! We all, indeed, shall not all sleep, yet we all shall be changed, in an instant, in the twinkle of an eye, at the last trump. For He will be trumpeting, and the dead will be roused incorruptible, and we shall be changed..." (1 Corinthians 15:51-52)
Biblical secrets/mysteries, are not unknowable, they are things left unrevealed until the proper time. The "secret" revealed above was that the dead will not "all sleep" but all will be changed from a corruptible body to an incorruptible, immortal body. The above "secret" and other secrets had been hidden from humanity until revealed to Paul...
"...since you surely hear of the administration of the grace of God that is given to me for you, for by revelation the secret is made known to me according as I write before, in brief, by which you who are reading are able to apprehend my understanding in the secret of the Christ, which, in other generations, is not made known to the sons of humanity..." (Ephesians 3:2-5)
Another "secret" reveled to Paul was that all nations, not just Israel, are to be the joint body of the Messiah/Christ Jesus.
"...in spirit the nations are to be joint enjoyers of an allotment, and a joint body, and joint partakers of the promise in Christ Jesus, through the gospel." (Ephesians 3:6)
Paul also revealed the "secret" that the blindness of Israel is temporary, "all Israel" will be saved...
"For I am not willing for you to be ignorant of this secret, brethren, lest you may be passing for prudent among yourselves, that callousness, in part, on Israel has come, until the complement of the nations may be entering. And thus all Israel shall be saved, according as it is written, arriving out of Zion shall be the Rescuer. He will be turning away irreverence from Jacob."
"For this corruptible must put on incorruption, and this mortal put on immortality. Now, whenever this corruptible should be putting on incorruption and this mortal should be putting on immortality, then shall come to pass the word which is written, Swallowed up was Death by Victory. Where, O Death, is your victory? Where, O Death, is your sting? Now the sting of Death is sin, yet the power of sin is the law. Now thanks be to God, Who is giving us the victory, through our Lord Jesus Christ. So that, my beloved brethren, become settled, unmovable, super-abounding in the work of the Lord always, being aware that your toil is not for naught in the Lord." (1 Corinthians 15:53-58)

(Romans 11:25-26)
Paul was "reproached" by the religious system of his day for sharing these secrets - and nothing has changed in the last 2000 years. Nevertheless, these secrets are still the true gospel we are to be "charging and teaching" our children, grandchildren and anyone else who will listen. They are "faithful" sayings even though they bring reproach from those who do not believe.
"Faithful is the saying and worthy of all welcome (for for this are we toiling and being reproached), that we rely on the living God, Who is the Savior of all humanity, especially of believers. These things be charging and teaching." (1 Timothy 4:9-11)
When all humans have "put on incorruption" and "immortality" they will have experienced the victory over death.
