Charles Spurgeon Commentary Revelation 1:8

"I am the Alpha and the Omega, saith the Lord God, who is and who was and who is to come, the Almighty." — Revelation 1:8 (ASV)

I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.

Happy is the man who thus, in reverent worship, hears God speaking to him in answer to his voice to God.
