How do we know that believers are redeemed and secure in Christ?

The security of believers is fundamentally rooted in God's Word, which reveals that redemption is complete through the blood of Jesus Christ. As stated in Hebrews 9:12, Jesus entered the holy place to obtain eternal redemption for us. He paid the ransom once and for all, assuring us that believers cannot be lost. The Apostle Paul in Romans 8:39 affirms that nothing can separate us from the love of God in Christ Jesus. This profound truth gives believers the assurance of their eternal security and underscores the sovereignty of God's saving grace, ensuring that all whom the Father has given to the Son will come to Him and be secured forever.
