NOT SO is the answer, the story of Sarah is the same like yours and mine. A lost cause, afterall the lady is in her 90’s, past menopause, medically done and over!. Not so Says GOD ALMIGHTY. To whom nothing is IMPOSSIBLE, to whom nothing is HIDDEN.
In the beginning God created the heavens and the earth. Therefore, just as through one man sin entered into this world, and through sin death: and so death passed upon all men, for that all have sinned. God so loved the world, that he gave his only Son, that whosoever believeth in him should not perish, but have eternal life.
