God the Father
We have all had fathers here on earth who disciplined us, and we respected them. So it is even more important that we accept discipline from the Father of our spirits so we will have life.
Hebrews 12:9 (NCV)
The writer of Hebrews makes a point in emphasizing that we all have human fathers. This illustrates the fact that fathers are representations of the Father of our spirits. We know that our human fathers dwell on this earth. Where, then, is the Father of our spirits? He should be in heaven.
“Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven.”
All Christians are familiar with this prayer. In addition to letting His disciples know what to pray for, he let them know how to address God. Jesus could have taught them to pray to God as Lord or Master, but He didn’t. Instead, He told them to call Him Father; this is why the prayer is famously titled, “Our Father.”
With this in mind, we can understand that the Father of our spirits is God the Father in heaven. Just as we have human fathers in the earthly family system, we have a Heavenly Father in the heavenly family system.
The title “father” implies that a man has children. Regardless of how old a man is, if he doesn’t have children, he can never be called a father. In the same way, if God the Father didn’t have children, we could not refer to Him as “Father.”
