That is absolutely false. I find each and every day is full of God's marvelous grace.
God says, If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land (2 Chronicles 7:14 NIV).
Our land cannot be healed, as SIN ad EVIL are growing...I think GOD heard Sarah, and wanted her for a different calling not the Land that is under the Wrath of GOD....
Then you are probably familiar with the only text written by Jesus Himself, the Book of Revelation?
