What does the Bible say about mysteries in a Christian context?

Biblical mysteries refer to truths that are concealed from the natural man and only revealed by God through His Spirit. This understanding differs significantly from contemporary ideas of mystery, such as those found in novels or movies, where the truth is discovered through human investigation. Paul conveys this in 1 Corinthians 15:51, emphasizing that the mysteries of God's kingdom, including our resurrection and eternal glory, are unveiled to those whom God chooses to reveal them. As believers, we recognize our spiritual blindness until God grants us revelation through His Word and the working of the Holy Spirit.
