Alpha and Omega
This concept refers to the first and last letters of the Greek alphabet and is especially significant as the most complete translation of the New Testament available is written in Greek. As far as Christianity is concerned, this concept is meant to denote the all-inclusiveness of God, His all-embracing quality, His greatness and Omnipotence.
Alpha and Omega refers to the beginning and end of Creation. In Revelations 22:13 we read, “I am Alpha and Omega, the beginning and the end, the first and the last.” The statement has to be examined in the context of who made it. Traditionally, people have assumed that this statement was made by Jesus. This statement, however, was not made by Jesus but by the Holy Spirit, Who is also the Son of Man. The fact that this statement did not emanate from Jesus can be seen in Revelations 1:4-5 thus: “Grace [be] unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne; And from Jesus Christ…”
The person speaking was obviously not Jesus since according to this statement He was also bringing Grace from Jesus. This is an entirely different personality Who has described Himself as the Alpha and Omega, the first and last, the beginning and the end. The point here is that this Personality is the First in the entire Creation, the first to appear and through whom the entire Creation came into being. If the entire Creation were to cease to exist He would also be the only one to remain, the Last, since He is eternal.
