Deuteronomy 4:30-31

When you are in distress, and all these things come upon you in the latter days, when you turn to the LORD your God and obey His voice
(for the LORD your God is a merciful God), He will not forsake you nor destroy you, nor forget the covenant of your fathers which He swore to them.

John 17:13-17

But now I come to You, and these things I speak in the world, that they may have My joy fulfilled in themselves.
I have given them Your word; and the world has hated them because they are not of the world, just as I am not of the world.
I do not pray that You should take them out of the world, but that You should keep them from the evil one.
They are not of the world, just as I am not of the world.
Sanctify them by Your truth. Your word is truth.

John 14:16-18

And I will pray the Father, and He will give you another Helper, that He may abide with you forever—
the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.
I will not leave you orphans; I will come to you.

Matthew 5:13-16

You are the salt of the earth; but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men.
You are the light of the world. A city that is set on a hill cannot be hidden.
Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house.
Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
