"Everything will be okay in the end. If it's not okay, it's not the end."
Jesus came to give us eternal life without pain or suffering, so that's why we can say "It is well", even when all is not well. This time of year is hard because it's the "happiest time of the year" but in reality, for some it's the hardest time of the year due to illness, the loss of loved ones, and other things. But with God, we can say "all is well", even when it's not. God is still faithful when things are not okay.
