I might agree that as we read in the various theophanies in scripture, the first and most striking attribute that man is met with, as Moses with the burning bush in Exodus 3 and then Isaiah 6, is the holiness of God. We see Moses is completely humbled by his sense of God's holiness. Isaiah, is totally undone. He says, "Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!” Holiness is the dominant attribute which opens their eyes to their own lack of holiness.
However, it occurs to me that as it is God who presents himself to man through his name, "I am who I am" I Am has sent you. His giving of His name to man, God sets forth His preeminence as His preeminent attribute. So this is how He wants His people to know Him.
Exodus 3:3 Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” 14 God said to Moses, “I am who I am.” [1] And he said, “Say this to the people of Israel, ‘I am has sent me to you.’”
This of course, is not to say that God's other attributes do not, as was said above,
"Ferguson said: That all the attributes of God inform all the others attributes."

I think that it does a person's soul good to contemplate the nature of God and that including His attributes.
