"And now, because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters; for behold, this day he hath spiritually begotten you; for ye say that your hearts are changed through faith on his name; therefore, ye are born of him and have become his sons and his daughters."
Through Spiritual rebirth we are called "children of Christ". If we "become his sons and daughters" by spiritually being "begotten", who then has become our "father in heaven"?
Our relationship to Christ can become a family relationship. The way we speak and interact would become much more personal. Many circumstances call for titles and appropriate respect, but if that is our only lifeline to heaven than that may just create an unnecessary suffocating barrier. I do not believe in a distant God who demands and coerces to gain respect. I believe in a God who invites us to know Him personally. The respect He then draws does compel my humility but not due to coercion, it's due to His light, goodness and overwhelming love.
The Spanish language has a familiar form of the "you" personal pronoun which is "tu". That's the word that is used in prayer when communicating with God. I remember learning to pray in Spanish and asked my teacher if I should use the formal respectful pronoun for 'you' which is "Usted". My teacher responded that I could but prayers are in the familiar form so I should use Tu. Familiar form, coming from the root word Family. I didn't catch that then, but I do now. I'm grateful to have learned a foreign language and begin to see in reality how many ways and on how many levels God desires to communicate on a personal level. Not so much a formal one. Some vocabulary habits and verbal traditions of the English language are not super helpful.
Many I interact with seem to want to endlessly maintain a very formal relationship in their prayers. Regardless of the words and pronouns, it's very formal. However God does not seem to share this view or desire we always remain at such a distance.
