Revelation 21:6-7

And He said to me, “It is done. I am the Alpha and the Omega, the Beginning and the End. To the one who thirsts I will give [water] from the fountain of the water of life without cost. [Is 55:1] He who overcomes [the world by adhering faithfully to Christ Jesus as Lord and Savior] will inherit these things, and I will be his God and he will be My son. [2 Sam 7:14; 1 John 5:5]
