Isaiah 54:8-10 ESV
In overflowing anger for a moment I hid my face from you, but with everlasting love I will have compassion on you,” says the Lord, your Redeemer. “This is like the days of Noah to me: as I swore that the waters of Noah should no more go over the earth, so I have sworn that I will not be angry with you, and will not rebuke you. For the mountains may depart and the hills be removed, but my steadfast love shall not depart from you, and my covenant of peace shall not be removed,” says the Lord, who has compassion on you.

Isaiah 43:2 ESV
When you pass through the waters, I will be with you; and through the rivers, they shall not overwhelm you; when you walk through fire you shall not be burned, and the flame shall not consume you.

Jeremiah 29:11 ESV
For I know the plans I have for you, declares the Lord, plans for welfare and not for evil, to give you a future and a hope.

John 16:33 ESV
I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.”
