Sometimes, when I'm flying home, the pilot has to wait to park the plane because the ground crew isn't there yet. The pilot needs the ground crew to direct the plane and ensure it's safely parked. They need to direct him.
The Israelites had the advantage of having God direct their journey. God appeared in a pillar of fire by night and a pillar of cloud by day, constantly guiding the people so they'd know where to go.
Did that make it easy?
Based on the amount of grumbling they did over the next few years, it clearly didn't serve as a constant reminder of all that God had done for them. They forgot, and they grumbled.
So let's not assume that it was any easier for anyone. It's always tough, because we see opposition and forget about the God who is with us. God sends reminders, although in these days it's often not such visually obvious ways, but God still reminds us. So let us keep our eyes and the eyes of our hearts open for what God has in store for us.
