6 Then He said to me, “It is done. I am the Alpha and the Omega, the beginning and the end. I will give water to the one who thirsts from the spring of the water of life, without cost.
7 The one who overcomes will inherit these things, and I will be his God and he will be My son.
8 But for the cowardly, and unbelieving, and abominable, and murderers, and sexually immoral persons, and sorcerers, and idolaters, and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death.”
Revelation 21:6-9
God says that only those who hunger after righteousness will receive it. God thrusts this heavenly manna on no one. You must desire it, above everything else. Your yearning for God must supersede all other desires. It must be like a gnawing hunger and a burning thirst.
