How do we know that suffering is necessary for believers?

The sermon explains that believers are called to endure suffering as a means of spiritual growth and to develop their faith. Romans 5:3 states that we should rejoice in our tribulations because they produce patience, experience, and hope. Suffering serves not only to test our faith but also to refine it, prompting us to lean on Christ and recognize our need for His grace. Just as Christ learned obedience through His suffering, believers also learn profound truths and the grace of God through their trials, ultimately leading to greater endurance and hope in Him.
