Scripture promises that heaven will be a realm of perfect bliss. Tears, pain, sorrow, and crying will have no place whatsoever in the New Heaven and New Earth. It is a place where God’s people will dwell together with Him eternally, utterly free from all the effects of sin and evil. God is pictured as personally wiping away the tears from the eyes of the redeemed. Heaven is a realm where death is fully conquered (1 Cor. 15:26). There is no sickness there, no hunger, no trouble, and no tragedy. Just absolute joy and blessings. It is frankly hard for our minds, which have never known anything but this sinful life and its calamities, to imagine.
John MacArthur
