'Hidden' in the Bible

But it is from Him that you are in Christ Jesus, who became to us wisdom from God [revealing His plan of salvation], and righteousness [making us acceptable to God], and sanctification [making us holy and setting us apart for God], and redemption [providing our ransom from the penalty for sin],

Yet we do speak wisdom among those spiritually mature [believers who have teachable hearts and a greater understanding]; but [it is a higher] wisdom not [the wisdom] of this present age nor of the rulers and leaders of this age, who are passing away;

but we speak God’s wisdom in a mystery, the wisdom once hidden [from man, but now revealed to us by God, that wisdom] which God predestined before the ages to our glory [to lift us into the glory of His presence].

For God has unveiled them and revealed them to us through the [Holy] Spirit; for the Spirit searches all things [diligently], even [sounding and measuring] the [profound] depths of God [the divine counsels and things far beyond human understanding].

So do not go on passing judgment before the appointed time, but wait until the Lord comes, for He will both bring to light the [secret] things that are hidden in darkness and disclose the motives of the hearts. Then each one’s praise will come from God.

For one who speaks in an unknown tongue does not speak to people but to God; for no one understands him or catches his meaning, but by the Spirit he speaks mysteries [secret truths, hidden things].

Listen very carefully, I tell you a mystery [a secret truth decreed by God and previously hidden, but now revealed]; we will not all sleep [in death], but we will all be [completely] changed [wondrously transformed],
