When President Ronald Reagan was sworn into office on January 20, 1981 he used his mother’s bible. The bible was opened, on purpose to this verse on purpose.
2 Chronicles 7:14
King James Version (KJV)
14 If my people, which are called by my name, shall 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.
He was a great president.
