In the Book of Revelation it says to count the number of the Beast, for it is the number of a man, his number is 666. The Greek language (the language of the New Testament) does not have a numeral system. Rather, it uses the alphabet. Each letter has a corresponding number. The name of Jesus in Greek equals 888. It does not equal 777.
Coincidentally, 888 is three infinity symbols, and it's written that "in Him (Jesus) dwells all the fullness of the Godhead bodily".
It's a neat little observation, and there is nothing wrong with that sort of thing in the proper context. But I would warn against attaching any real spiritual or doctrinal significance to any of this. Our focus should be on God and His Word. Nowhere in the Bible are we taught to observe numerology or to incorporate numerology into our worship or study of God. In fact, we are warned against that sort of thing. We should stick to the Gospel and the simplicity in Christ, and only emphasize what is revealed in the Word of God when it comes to our serious study and worship of God.
