In Avengers: The Age of Ultron, the Scarlet Witch plays upon the Avengers fears to divide and conquer them. United they are an unconquerable force, but pinned against each other they are vulnerable.

Tony Stark: Does anybody remember when I put a missile through a portal, in New York City? We were standing right under it. We’re the Avengers, we can bust weapons dealers the whole doo-da-day, but how do we cope with something like that?

Steve Rogers: Together.

Tony Stark: We’ll lose.

Steve Rogers: We do that together too.

There is great power in unity, which is why the forces of evil in our favorite fandoms (and in life) seek to conquer by first spreading discord and disunity…

I say to you all, once again — in the light of Lord Voldemort’s return, we are only as strong as we are united, as weak as we are divided. Lord Voldemort’s gift for spreading discord and enmity is very great. We can fight it only by showing an equally strong bond of friendship and trust. Differences of habit and language are nothing at all if our aims are identical and our hearts are open. ~ Dumbledore, Goblet of Fire

But how do we stay united against forces like that of the Scarlet Witch (under Ultron) and of Voldemort? Both were able to turn friend against friend (Iron Man v. the rest of the Avengers / Ron against Harry) by playing on individual fears and insecurities. Dumbledore says the only way to fight this spread of discord in through strong bonds of friendship and trust. And he is right on with what the Bible tells us to do…

…I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one: I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me. ~ Jesus’s Prayer, John 17:20-23 NIV
Beyond all these things put on love, which is the perfect bond of unity. ~ Colossians 3:14 NASB

Unity brings us power; and the way to have that unity is by putting on love. Ron came back to Harry and Hermione because of love, they reunited stronger than ever, and conquered Voldemort—the one who sought to divide them. The Scarlet Witch (serving Ultron) brought division to the Avengers, but love—their love of others and of each other—reunites them and powers them to defeat Ultron.

How much evil could we rid the world of if we all put on love?

Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.

Love never ends. ~ 1 Corinthians 13:4-8 ESV

We know how much God loves us, and we have put our trust in his love. God is love, and all who live in love live in God, and God lives in them. ~ 1 John 4:16 NLT

Be a superhero—put on love, put on God.
