Revelation 2:26; Revelation 21:6; Revelation 22:13

26 And he that overcometh , and keepeth my works unto the end, to him will I give power over the nations:
6 And he said unto me, It is done . I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
13 I am Alpha and Omega, the beginning and the end, the first and the last.
