Remember that God loves you and wants to save you and share everlasting life with you in Heaven.
Philippians 4:6-8 (New International Version)
6Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. 7And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
8Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
John 3: 16"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17For God did not send his Son into the world to condemn the world, but to save the world through him. 18Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son. 19This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. 20Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. 21But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."[h]
You quoted John 3:16. You can find that in the Bible. However, the workings of the Trinity are suggested in the Bible (especially in Matthew and mostly in John) but not fully explained (they are a profound Mystery). These things were worked out in the earliest days of the Church by the Church Fathers and virtually all Protestant denominations defer to the Catholic Church in this understanding since to do otherwise is to fall into Arianism and an entire panoply of errors (see Hillaire Belloc, "Heresies").
Thus, do you believe that God is Co-Eternal with Three Persons: God the Father, God the Son and God the Holy Spirit in one Divine Nature? Those are the rudiments of the Trinity. If then God the Son was "incarnated" taking on human flesh, He was a Divine Person, God the Son, with two natures, Divine and Human, and was born of Mary, a human. Thus, she gave birth to the Son and is the Mother of God which was the point under discussion.

BTW: You are the street lawyer. Common Law states that silence is construed as "assent" and not negation. That I didn't answer you should convey assent unless I do respond negatively.
