And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. (Revelation 21:4)
What a most marvelous Scripture we have here. What insight into our eternal future. It seems to embrace all the heaviness of this life and to reveal in part the bliss, the Paradise, the riches of eternal life. But how can this help us in our present life?
I see here the nature of our God and Father. It's brilliance shining in every word. He is compassionate. Touched with our infirmities. Father God knows every tear you or I have shed. Every sorrow we have endured. Every painful happening that occurred in our whole life. Like no one else, even deeper than our own thoughts; God is there

So when we make prayers, let our hearts be lifted, knowing  whom you are speaking to. Through your present tears, sorrows and pains; there is a hand that is not shortened. It's no wonder Jesus advises us to, "pray always!"
