No it's not literal. Wow are you saying something horrific. That's your own creation. God doesn't have children and neither does he have chromosomes. God is unlike us. God have mercy, where do you get this stuff from?
God is literally the Father of the Son. But dont take my word for it. Ask Him.
God is very much like us. We were created in His Image. We are His children. We know Good and Evil like He does.
There are differences. He is immortal and glorified. We are currently in our mortal probation. We sin, He doesnt. It's because of death and sin that we are currently separated from God. Those two obstacles are impossible for us to overcome on our own.
That is why God had a plan from the beginning of Creation. That is why He ordained Christ to come in the meridian of time. He established a Savior for us from before the World was. Because in His infinite wisdom, He knew that we would need help overcoming death and sin.
Christ came in the Meridian of Time. He inherited the ability to die from His Mother. He inherited the ability to rise from His Father. He lived a perfect life as our Example in all things. He organied His Church and ordained Apostles, Seventies, and other leaders to preach the Gospel and reconcile us with God.
And then He gave His life in the ultimate sacrifice for sin. The one person who could choose not to die, who did no sin to deserve death, offered Himself up as a sacrifice for all of those who could not overcome death and sin. And because of Him, every single one of us who lives will live again despite our death. Despite our mortality, in our flesh we shall see God.
Because of His sacrifice, we can also gain Eternal Life. He provided us with a new covenant to reconcile us with God so we can be forgiven of our sins and imperfections. Because of Him, we can be healed.
This is the Plan of Happiness and Redemption. This is the Gospel that God has taught since the beginning of the world through the Ministering of Angels, through the testimony of the Holy Spirit, and by His own words. And He invites you, and everyone else who hears this message to humble themselves before Him. Ask God in the name of the Son and you will recieve your own witnesses that Jesus Christ is the Son of God. It's the only way to know the truth.
We can all learn the truth by the grace of God. You just have to have faith enough to ask. I didnt know Jesus was the Son of God when I asked. I didn't even know if there was a God. But He is merciful. He wants you to come to Him. He wants you to ask and learn for yourself. I did, though I am nothing special. And now I do know that The Father lives. I know that Jesus Christ is literally His Son. And He now stands on the Right hand of the Father.
Don't be afraid, ask in Faith instead. Submit to the Lord and He will teach you things you never comprehended or imagined. The time will soon come when He will establish Zion among us. Join us in His work. You will see miracles. I have. And I dont think Ive seen close to half the things that are possible.
Joking, of course.
