Life will always be victorious over death. That doesn't mean we're not going to die. We all will die. That doesn't mean that if we believe in Jesus, we're never going to suffer, never going to experience pain or loss, because we will experience all of those things. What has been revealed to us in Jesus' death and resurrection is that the death and the pain and the suffering and the loss are never the last word.
Love can always overcome.
The relationships will never be broken because what has been lived and loved cannot be lost. When we celebrate Christmas and the promise of a brand new baby, we also have to remember that all of that hope ended with arrest and crucifixion. It ended with pain and sorrow until God had the last word. We find it very easy to get excited about Christmas. We love gatherings with friends and family, sharing presents, extending generosity to strangers.
