I watched with sadness this documentary. It broke my heart that these people have given up on God simply because things didn't go as THEY planned them. That's not the way Christianity works, we follow God's plan. Life isn't always rosy, but He gives us strength, courage and trust to continue on.
I found myself praying for various individuals throughout this video.
My heart tells me Brendon's wife is not happy where she is with her faith. She wants to come back, but can't figure out how without hurting her husband. Come back, perhaps he'll follow. You owe it to your children. Don't drag them down with you. You know what penalty non-believers pay. Do you really want that for your kids? Please don't think "They're young, they can decide later". Only God, yours and mine, know a person's time on earth.
Come home.
