Almost every sinful action ever committed can be traced back to a selfish motive. It is a trait we hate in other people but justify in ourselves.

There must be a stronger foundation than mere friendship or sexual attraction. Unconditional love, agape love, will not be swayed by time or circumstances.

Alex [Kendrick] and I started out the whole film-making journey as a desire to reach people for Christ and try to impact their lives for him.

In churches, we see that getting people to show up for a prayer meeting is a lot more difficult than a concert or service project or just about anything else. So we were thinking, we're stepping into some unknown territory here that could be as profitable, or it could be a box-office flop, but there was a rightness about it. And so this whole idea of the war room being like a spiritual warfare room, a place of prayer where you get alone with God and you're making your decisions and you're dealing with your issues first in prayer.

We grew up in a praying home [with Alex Kendrick], we saw incredible answers to prayer in our parents' lives, they grew up in praying homes, our father launched a Christian school with nothing, basically he had some people that believed in the project but they had very little resources, and we watched our parents deal with those issues first in prayer, and then when they went out knocking on doors they saw amazing doors answered and resources come in.

That word is 'willing.' It's an attitude and spirit of cooperation that should permeate our conversations. It's like a palm tree by the ocean that endures the greatest winds because it knows how to gracefully bend.

Nobody knows you as well as our spouse. And that means no one will be quicker to recognize a change when you deliberately start sacrificing your wants and wishes to make sure his or her needs are met.
