How do we know that God's plans cannot be thwarted?

The certainty that God's plans cannot be thwarted is grounded in His immutable decree, as stated in Isaiah 46:9-11. God has purposed all things, declaring their end from the beginning. His omnipotent will ensures that everything unfolds according to His divine counsel. Additionally, Romans 11:36 affirms that all things are from Him, through Him, and to Him, implying that God’s purposes are ultimate and will come to fruition despite any opposition. Understanding this encourages believers to trust in God's providential guidance and the certainty of His promises.
