Isaiah 63:9 In all their distress, it was no messenger or angel but his presence that saved them.

The prophet is reminding the people of their past history—reminding them that God went with them into the desert and crossed over the Red Sea with them. He was present in a pillar of fire by night and a pillar of cloud by day, leading them and guiding them. After awhile, they forgot about God as we all so often do—when things are going great and we’re no longer in danger or a crisis. He is with you now—and will save you still, just like those days long ago.
