How do we know that God can bring good out of sin?

In Moses' life, we see that although he acted in sin by murdering the Egyptian, God used this event in Moses’ life to humble and prepare him for a greater mission. This illustrates that God's sovereignty ensures that even when we fail, He can orchestrate circumstances to produce good outcomes, fulfilling His divine purposes. While our sins do not excuse us, God’s grace overcomes our failures, leading us to a deeper reliance on Him. This doctrine of God's sovereignty teaches us that our shortcomings ultimately serve to highlight His mercy and power.
