Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal. 2 Corinthians 4:16-18 NIV
How can you keep smiling when going through difficult times? We can, you know because we know Jesus is walking by our side during the darkness of this world. We have faith because we know whatever we go through is just temporary. We know something better is coming. Don’t be distracted by what is going on around us – we must keep our eyes on Jesus. He is what we trust in that keeps us going.
