How do we know that God uses our past for His purpose?

Our past experiences are not wasted in God's economy; instead, they are part of His divine preparation for our lives. As seen in Moses's story, the years he spent in Egypt and then in the wilderness were instrumental in forming him into the leader God needed him to be. God's grace is evident throughout Scripture, which assures us that nothing is without purpose. Romans 8:28 tells us that all things work together for good to those who love God, demonstrating that our past, no matter how painful or wandering, contributes to His greater plan. Likewise, he uses our life's circumstances to teach, mold, and develop us into useful vessels for His glory.
