Our Father Which Art in HeavenFather is the foundation of the family. Biblically speaking, you cannot call father who are not in heaven.
"And call no man your father upon the earth: for one is your Father, which is in heaven." (Matthew 23:9)Believe it or not, it was a Law of a true Christian disciple. When you call the person a father in this world, you are disobeying the will of God. The only one we can call father, is the Father who are in heaven.
