Eternal security is assured by God's promise to keep believers through faith, as seen in 1 Peter 1:5 and supported by Christ's intercession for His people.
The doctrine of eternal security is grounded in scriptural assertions that God is able to keep His people safe in Christ. In 1 Peter 1:5, it specifies that believers are 'kept by the power of God through faith.' This implies that God's sovereign power ensures that the elect will not fall away, despite temptations or trials. Additionally, Christ’s continuous intercession as recorded in John 17 and other passages reinforces this promise, asserting that He will not lose any that the Father has given Him. The reality of God's sustaining power and His faithfulness in keeping His promises assures us that true believers will persevere until the end.
