They are all different, but they are all centered, and can speak to anyone about what they think, and what they believe.
I love Reagan, and one reason that I think his faith was deep, was the fact that he could remain real and humble while also being a King, Reagan had it all, his physical courage as a regionally famous life guard and as a 5 year Cavalryman, his speaking abilities, his looks, his entire life of being wonderful and most of it wealthy, yet he was always, Reagan, the man.
Cruz is similar, Cruz the genius, Cruz the famous debater, Cruz always the brightest man in the room and a wonder, but also Cruz, the simple Southern Baptist Christian.
Palin is like that.
Exceptional human beings and politicians who are Christ anchored, which keeps them grounded and focused on the goal of helping America and their fellow man, as they use their talents to enrich more than just themselves.
Your post is very insightful. You make the most valid point, that the real factor with Reagan, Palin and Cruz is FAITH. Some may, as this author does, confuse that with arrogance, when it is truly the unwavering belief in God and trusting Him for Wisdom. They know that, “If any man lacks Wisdom, let him ask of God, Who will give to him liberally, and upbraideth not”. That is where their confidence is, in God, not man. I Love it!
