Why is it important for Christians to build themselves up in faith?

In Jude 20, believers are instructed to build themselves up on their most holy faith through prayer and dependence on the Holy Spirit. This strengthening process involves engaging with Scripture, fellowship with other believers, and maintaining a continuous prayer life. By focusing on Christ as the object of our faith, we gain conviction and strength to withstand challenges and the allure of false teachings. Spiritual maturity is crucial for navigating the complexities of the faith journey, allowing believers to grow in grace and knowledge of our Lord Jesus Christ.
