Spiritual growth is an intentional journey that requires commitment to specific disciplines and practices. Based on Paul's letter to the Colossians, growing in faith involves three essential elements: faith in God's power to do the impossible, love as our response to Christ's sacrifice, and hope in our eternal future with God. Our beliefs directly shape our behavior, our trust affects our life's trajectory, and our confidence in God influences our outcomes. This growth happens through practical disciplines like Bible study, prayer, worship, fasting, giving, serving others, and regular church attendance. Mature believers have a responsibility to guide newer Christians in their spiritual journey, helping them develop from spiritual infancy to maturity.
