Before watching the video, bahmer,
let me assure you my reason for believing that God is a He is not based on anything other than His own revelation to mankind known as the Bible.
Written in it's entirety through Jewish Prophets, then Christian Apostles, as inspired by God, the Holy Spirit, using the words given Him by Jesus, who is God, the Son; in the Bible, God is never referred to as she or it, but is always referred to as "He."
Because God refers to Himself as He, I refer to God as He.
He, being God, knows who He is.
I did just watch the video, and am disappointed in Dennis Prager, whom I usually admire. Instead of quoting Scripture, he used as references 1) Barack Obama, a self-worshiping deviate, and
2) a Psychiatrist from Harvard University.
IMHO, the goal of the Bible is to provide mankind a solution for their sin-nature alienating them from God, through the crucifixion, burial and resurrection of Jesus Christ.
That does not create a gentler environment, for as Jesus foretold, all the world hates Christians.
