What does the Bible say about building up our faith?

In Jude 20, believers are instructed to build themselves up on their most holy faith, which involves growing in the knowledge of the Lord Jesus Christ. This growth is likened to a building, where the foundation is established on the teachings of the apostles and prophets, with Christ as the cornerstone (Ephesians 2:19-20). Additionally, in 1 Peter 2:5, believers are described as living stones in a spiritual house, indicating an active and dynamic growth in faith. This responsibility to grow in faith emphasizes the importance of being saturated in God's Word and leaning on His promises for guidance.
