It is completely reasonable and logical. Every propositional conclusion begins with a presupposition; from that presupposition comes proposition and premise and from those propositions and premise comes a conclusion. If at any time your proposition and premise diverts from the presupposition, it is illogical and unreasonable.
Everything in life, whether philosophical or scientific, comes from a presupposition and from those presuppositions comes proposition and premise and from these propositions and premises comes conclusions. Whether it is a true propositional conclusion is based on whether the propositions remains true to the presupposition. Logic is what proves or disproves the propositional conclusion being true based on the initial presuppositions.
So the presuppositions:
-A guy is born a virgin
-Humanity has sinned, is possible.
-A guy took upon himself the sins of humanity through his death
-A guy raises from the dead three days later proving his authority over death.
If you believe any of those presuppositions, then every proposition and premise that comes from them must remain constant and logical based on these presuppositions, otherwise they are flawed and faulty.
So, I would rethink your belief concerning logic since a guy who is born from a virgin to save humanity from his sins reconciling them through his death and giving them life through his resurrection is completely logical and reasonable based on the presupposition that these things occurred and that these are indeed true facts which are known even if they have yet to be demonstrated through scientific means.
It becomes a possibility, RanRan, you may not understand philosophy nor do you understand logic concluding you may not know what you think you know and that is the logical conclusion concerning your beliefs on logic (you most certainly may have an idea of other things you believe).
John 1:1 In the beginning was Logos, and Logos was with God, and the Logos was God.
A particular word used, Logos, the appeal based on logic or reason and is the controlling principle of the universe and that Logos became flesh and dwelt among us.
John 1:14 Logos became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.
For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
As a result of this understanding, everything I believe is on a sure foundation, which is reasonable logical and sound.
1 Corinthians 3:11 “For no one can lay any foundation other than the one already laid, which is [the Word (Logos)] Jesus Christ. But each one should be careful how he builds upon it.”
