What does the Bible say about God's effectual will?

God's effectual will guarantees that those whom the Father has given to Christ will not be lost, as stated in John 6:37-39. Jesus emphatically declares that all the Father gives Him will come to Him, and He will raise them up at the last day. This security is rooted in God's sovereign and unchangeable purpose. According to Ephesians 1:4-5, God chose His elect before the foundation of the world, ensuring that their salvation is secured by His will and grace, and not dependent on human effort or belief. The assurance that none will be lost showcases the robust nature of God's redemptive plan.
