Did you know that English is the only language in which the 1st person singular pronoun is capitalised? I only learned this recently and haven't confirmed it but, according to my limited knowledge of other languages (je, ich, yo, io, ego), it appears to be true. It undoubtedly has some significance, reinforced by the fact that the letter 'I' is like the numeral 1.
The significance, as I see it, is that the English-speaking peoples were those who were most conscious of themselves as individuals and, by extension, most concerned with personal liberty. These are actually highly spiritual matters because individuality is what makes a created being start to become a god in its own right and the sense of personal liberty is what gives a material being release from the control of matter into the freedom of spirit. This is why the Creator created, to make, to put it somewhat naively, friends and companions as opposed to mindless slaves.
Now, the process can go wrong. If individuality becomes important for its own sake and seeks to serve itself rather than God it has, so to speak, gone bad. But if it aligns itself with the creative purpose of the universe and seeks harmonious interaction with other individuals, it is carrying out God's will and furthering its own spiritual fulfilment.
By this line of thinking it would be no accident that English became a kind of universal language in the 19th and 20th centuries and continues to be so. The gift of individuality, hitherto present but relatively undeveloped, spread throughout all the nations of the world. This was a major step forward in human evolution. Now what is needed is for this individual sense of self to connect with the greater Self of the universe. Having become conscious of itself it needs to learn to go beyond itself but it could not do this without first knowing itself. It is the sense of separation that allows for fully conscious union.
I is the basic reality if the universe. It is how God would describe himself. I, the 1 without a second. It is what consciousness reduces to. The eternal subject. God's great gift to his creation was to bestow his supreme sense of self on us human beings so that we could become like him. This is what being made in his image means and it is an idea expressed in English more fully than in any other language. This was the task of the English speaking peoples, to give the world a full sense of what it is to be an individual.
