Sure

What are you sure about?

Ruth 1:16-18
Ruth replied, "Don't ask me to leave you and turn back. I will go wherever you go and live wherever you live. Your people will be my people, and your God will be my God. I will die where you die and will be buried there. May the LORD punish me severely if I allow anything but death to separate us!"

Romans 8:35-39
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 are hungry or cold or in danger or threatened with death? 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 his love. Death can't, and life can't. The angels can't, and the demons can't. Our fears for today, our worries about tomorrow, and even the powers of hell can't keep God's love away. Whether we are high above the sky or in the deepest ocean, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord.

2 Timothy 1:12
And that is why I am suffering here in prison. But I am not ashamed of it, for I know the one in whom I trust, and I am sure that he is able to guard what I have entrusted to him until the day of his return.
