YOLO (You Only Live Once). This phrase is often used to justify people having a good time or splashing out or indulging themselves.
Christians believe in two lives: our life here on earth (our mortal life) and an immortal life with God that continues beyond our present body. Like the YOLO phrase points out though, we each only have one mortal life so we ought to make the most of it.
Hang on. If Christians believe that God will come and make everything right at the end of time, why does it matter how we live now? Also, if we know God is a forgiving God, can't we just do our own thing for the time being and repent and come closer to God later in our lives?
There are two problems with this. One is that none of us knows how long we will be alive. The other problem is that this attitude doesn't fit with being a friend of Jesus. Christians are those who are 'on board' with Jesus, caring about what he cares about, being transformed by him and helping transform the world.
On the first Sunday in Advent, many Anglican churches use a prayer based on Romans 13:11-14. The prayer reminds us that we need to pay attention to how we live our 'one life on earth' rather than just waiting for what God will do at the end of time and waiting for our future immortal lives. The prayer contains these words:
Give us grace to cast away the works of darkness
And to put on the armour of light
Now in the time of this mortal life...
You will only live on this earth once. How do the phrases 'works of darkness' and 'put on the armour of light' relate to your one opportunity at life?
