How do we know God's plan in our trials is true?

The assurance that God's plan in our trials is true comes from the understanding of His sovereignty and love for His children. Romans 8:28 reminds us that all things work together for good for those who love God, affirming that even the heaviest afflictions serve His greater purpose. Every hardship is known by Him, and He appoints them in number, weight, and duration for our good. Thus, when we see trials through the lens of His overarching plan, we can confidently trust that they are a means to refine us for holiness and an eternal weight of glory.
