1 Corinthians 13:13

Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful.

Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows.

For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.

Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; 

 The Lord appeared to us in the past, saying:

“I have loved you with an everlasting love;
    I have drawn you with unfailing kindness.

I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing.
