How do we know God's purpose will be accomplished?

God's sovereignty ensures that His purposes will undoubtedly come to fruition. The Scripture reminds us that the plans of the Lord will prevail, regardless of human unbelief or circumstances. As demonstrated in the story of Zacharias, God’s promises are fulfilled in their time, and no amount of doubt can thwart His divine will. Paul affirms this in 2 Timothy 2:13, saying that even if we are faithless, He remains faithful, indicating that God's character guarantees the accomplishment of His plans.
