"But what does it all mean?" asked Susan when they were somewhat calmer.
"It means," said Aslan, "that though the Witch knew the Deep Magic, there is a magic deeper still which she did not know. Her knowledge goes back only to the dawn of Time. But if she could have looked a little further back, into the stillness and the darkness before Time dawned, she would have read there a different incantation. She would have known that when a willing victim who had committed no treachery was killed in a traitor's stead, the Table would crack and Death itself would start working backwards." (From the book - The Lion, The Witch, and the Wardrobe)

You have heard from the book of The Lion, The Witch, and the Wardrobe - now hear from a few other books.

1 Peter 1:20 - "He [Jesus] was chosen before the creation of the world,..."

Revelation 13:8 - "...the lamb that was slain from the creation of the world."

Ephesians 1:4 - "For he [Father God] chose us in him [Christ Jesus] before the creation of the world to be holy and blameless in his sight."

 Love is not magic.  Love was the made-up mind of The God from everlasting to everlasting (Nehemiah 9:5; Psalm 90:2; Habakkuk 1:12).  In three places, (Revelation 1:8, 21:6, and 22:13) God refers to Himself as the Alpha and Omega, the one who is the beginning and who is the end.  He is before all, through it all, at the end of it all, and beyond it all.  However, before the creation of the world, God had The perfect sacrifice in mind to display His perfect love - The Logos, His Word.

Father God's Word has always been with Him.  For "In the beginning was the Word, and the Word was with God, and the Word was God.  He was with God in the beginning." (John 1:1-2)  The Father, Word, and Spirit of God all live in harmony within the mind and heart of Father God.  Anytime Father God speaks, God's Word performs Father God's thoughts perfectly as He, The Word,  is uttered from God the Father's lips (i.e. - "Let there be light and there was light..." - Genesis 1:3) -  "Through him all things were made; without him nothing was made that has been made." (John 1:3).

However, according to the Scriptures above (1 Peter 1:20; Revelation 13:8; Ephesians 1:4) there must have come a time before the creation of the "world" or in the Greek, Kosmos (ordered systems, solar system, universe, society, governments, kingdoms, etc..) when Father God's thoughts turned to The Plan.  A design, that when pictured in God's mind saw His Word becoming flesh, wounds appearing upon His body, nail scars emerging on His hands and feet, grooves on His brow from the Crown of Thorns, and the divot of flesh from His pierced side.

Father God decided before creating that His Word would become His creation - human, Yeshua (Jesus).  The Word (Jesus) was chosen before the creation of the world (and IMHO, before the creation of the Angels and their hierarchy) as His vessel of salvation (1 Peter 1:20).  All of humanity was who Father God designated as those "he chose in Him [Christ Jesus] before the creation of the world to be holy and blameless in His sight." (Ephesians 1:4) The Choice to accept Him (Jesus) as God's sacrificial gift of restoration was placed in our hands.  Father God, The Word, and The Holy Spirit all viewed the idea of Yeshua (Jesus) defeating Satan before there even was a Lucifer or at least a created world by the imagery of a slain lamb in the mind of God (Revelation 13:8).

Father God's thoughts of love and sacrifice became reality and manifested in the man Yeshua or translated for today - Jesus.  The Old Testament Law (Law of Moses) was created to show the severity of our condition.  However, Christ came as that ultimate, perfect sacrifice which would usher all who believe in God's gift into a restored relationship by grace through faith.  "For Christ did not enter a man-made sanctuary that was only a copy of the true one; he entered heaven itself, now to appear for us in God's presence. Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself." - Hebrews 9:24-26

You see Father God thought everything through - creation, salvation, eternity, everything - "Suppose one of you wants to build a tower. Will he not first sit down and estimate the cost to see if he has enough money to complete it? For if he lays the foundation and is not able to finish it, everyone who sees it will ridicule him, saying, 'This fellow began to build and was not able to finish.' "Or suppose a king is about to go to war against another king. Will he not first sit down and consider whether he is able with ten thousand men to oppose the one coming against him with twenty thousand? If he is not able, he will send a delegation while the other is still a long way off and will ask for terms of peace. In the same way, any of you who does not give up everything he has cannot be my disciple. - Luke 14:28:33  This says Father God "sat down", considered the cost, and decided the plan to give up everything (His Word made flesh or human) to display the extent of His love was worth it all.  Verse 33 says if you are not willing to "give up everything" as the Savior has then Christ says to that person "he cannot be my disciple".  With that kind of God - sacrificial love, even of His own Word or Son -  why not surrender everything to God by believing in Christ and His free gift of salvation?  The benefits are eternal and there are No Disadvantages to His Design - The Plan!
