Therefore he is able, once and forever, to save those who come to God through him. He lives forever to intercede with God on their behalf.
Hebrews 7:25 NLT
My dear children, I am writing this to you so that you will not sin. But if anyone does sin, we have an advocate who pleads our case before the Father. He is Jesus Christ, the one who is truly righteous.
1 John 2:1 NLT
Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself. Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God’s right hand, pleading for us. Can anything ever separate us from Christ’s love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death? (As the Scriptures say, “For your sake we are killed every day; we are being slaughtered like sheep.” ) No, despite all these things, overwhelming victory is ours through Christ, who loved us. And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord.
Romans 8:33-39 NLT
