What does the Bible say about building materials in faith?

In 1 Corinthians 3:9-15, Paul describes the various building materials available to believers: gold, silver, precious stones represent enduring qualities and the faithful proclamation of the gospel, whereas wood, hay, and stubble symbolize transient efforts that lack eternal value. This passage primarily addresses preachers but applies to every believer's life and ministry. The foundation is Christ, and what we build upon Him should reflect our genuine faith and understanding of His gospel. The 'building materials' signify the quality and manner in which believers live out their faith, which will be tested and revealed in the end.
