How do we know God's purposes are always accomplished?

Scripture emphasizes God's sovereignty in all matters, highlighting that He has specific purposes for everything under heaven, as seen in passages like Psalm 31:15, where David expresses trust that his times are in the Lord's hands. This assurance underscores that God's will is not thwarted by human actions or failures; rather, His purposes unfold according to His divine timetable. Every event, whether it be a time to plant or to uproot, ultimately stems from God's perfect foresight and omnipotence, assuring believers that He is working all things out for good.
