Dear friends, don’t be surprised at the fiery trials you are going through, as if something strange were happening to you. Instead, be very glad—for these trials make you partners with Christ in his suffering, so that you will have the wonderful joy of seeing his glory when it is revealed to all the world.
Even though we know verses like this, and we remember Jesus asked us to take up our cross and follow him, and that this following is the narrow way - we still come up surprised when we suffer for his sake in some way.
But this is a war we are in, and the enemy does not play fair. Life is hard, and there is no easy way out. So when life's trials hit, see it as a sign that Jesus is in control, and live for him daily. Meantime - do as this verse says - focus on the rewards, the future, the victory.
Amen (so be it).
