Why do believers need to have faith in Jesus?

In Mark 4:40, Jesus questions His disciples about their lack of faith, highlighting the importance of trusting Him in turbulent times. Faith is not merely intellectual assent but a deep-rooted trust in His character and promises. Believers are called to rest in His sovereignty, especially when circumstances are daunting. As Isaiah 54:11-13 encourages, those who are afflicted and overwhelmed can find peace through trust in God’s faithfulness. Faith enables believers to navigate trials with assurance that God is orchestrating all things for their good and His glory, reminding us that He is in control even during the storms of life.
