Why does Paul say nothing can separate us from God's love?

In Romans 8:35-39, Paul robustly declares that neither tribulation, distress, nor any other obstacle can separate the believer from the love of God in Christ Jesus. This affirmation is grounded in God's immutable nature and His steadfast commitment to His chosen people. Since God assures believers of His unending love and the reality of their salvation, no circumstance or adversary can undermine the relationship we have with Him. This passage underscores the confidence believers can have in the security of their salvation and that God's love sustains them.
