What does the Bible say about the eternal safety of believers?

The assurance of eternal safety for believers is rooted in Romans 8, which declares that nothing can separate us from the love of God. The verses in Zechariah 14:11 also affirm that Jerusalem shall be safely inhabited, representing God's promise that His people are secure in Him. This security does not hinge on our actions or failures but on the sustaining grace of God, reinforcing that true salvation brings eternal safety and assurance to those He redeems. Thus, believers can rest in the knowledge that their position in Christ is unshakeable and secure.
