How is the Logos person after incarnation?

I already searched in case my question has been questioned. But I cannot find it. From this link I read : > Question:
What does incarnate mean? How was Jesus God incarnate? > > Answer:
The Latin verb incarnare meant “to make flesh.” When we say > that Jesus Christ is God “Incarnate,” we mean that the Son of God took > on a fleshly, bodily form (John 1:14). > >However, when this happened in > the womb of Mary, Jesus’ earthly mother, He did not stop being deity. > Although Jesus became fully human (Hebrews 2:17), He retained His > status as God (John 1:1, 14). > > **How Jesus is able to be both man and God** > **simultaneously is one of the great mysteries of Christianity** To me, I don't find that *"The Logos is able to be both man and God simultaneously"* is a mystery at all. Here is why :
1. The Logos is God, eternal, infinite.
2. The Logos took on a fleshly, bodily form 3. However, when this happened in the womb of Mary, The incarnated-Logos earthly mother, The Logos did not stop being God.
4. So there are two existencies of one Person (The Logos), The Logos who still as fully God (without a form) and The incarnated-Logos as a fully human being inside the womb of Mary. To me, it's not a mystery because the Logos as God (without a form) is omnipotent. So, even if (for example) I add another Logos existency in a form of Theophany who appear somewhere in Timbuktu while at the same time the same Person as a human being (incarnated) inside the womb of Mary ... to me it's not impossible. Because the article said that *"How The Logos is able to be both man and God simultaneously is one of the great mysteries of Christianity"*, then it seems my four-points-opinion above is not correct. So my question is:
*In what way is the "great mystery" of it in the point of view of Christianity ?* PS:
whenever I read "Jesus" name in the article above, my mind "shift" to the eternal Logos, not to the incarnated-Logos inside Mary's womb.
