When the Exodus began, God gave his people a tangible vision of his presence (although he chose not to reveal himself as he really is). This continued all the way through the wilderness wanderings and all the way up to Moses' parting from his people:
"Then the LORD appeared at the Tent in a pillar of cloud, and the cloud stood over the entrance to the Tent." - Deuteronomy 31:15-16 (NIV)
This was not a small matter to the Israelites, because centuries later, it still remained a symbol of God's compassion for his people:
"Because of your great compassion you did not abandon them in the desert. By day the pillar of cloud did not cease to guide them on their path, nor the pillar of fire by night to shine on the way they were to take." - Nehemiah 9:19-21
What is remarkable to me is that you don't read about the pillar in the story of Joshua. When did the pillar of cloud leave? When God makes his exit, it is frequently a big deal (just look at his exit in Ezekiel 10 or Acts 1). But the scriptures never tell us when the pillar of cloud left. Don't you imagine that God's people had to wonder where God was? Don't you think that their children would be asking about it? I personally think that the pillar may have ceased to appear when the manna and quail stopped. After that, God's providence through the land became the symbol of his continual presence.
I believe that since then God has required incrementally more faith of his people. It was easier for those who had seen the mighty acts of God in the wilderness and the taking of Canaan than it would be for those who came later. The prophets, despite the things that they heard and saw looked forward to the things that would happen in the time of the Messiah: "For I tell you that many prophets and kings wanted to see what you see but did not see it, and to hear what you hear but did not hear it" Luke 10.24 (NIV). And finally, Jesus made it clear that "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed" John 20:29 (NIV).
Yet, at the same time, God has given his written word as evidence and the Spirit as a Comforter to allow us to maintain a faith that glorify him as surely (if not as largely) as Joshua's did. God grant us a childlike faith in his presence: simple, loving, and dependent.
Grace and peace,
