What is the significance of Christ's words to his mother in John 2:1-5?

Please distinguish the terms "vow", "oath", "swear" and "pledge." Some of these are interchangeable and some are referred to in the bible as totally different from each other. I'm specifically interested in what Jesus meant in Matthew 5:33-37 and how that applies to nowadays "pledging" for a building fund or other church projects.

Please give me a study report about the virgin birth (Isaiah 7:14) and its fulfillment in the New Testament.

I have a question/comment about the trinity. Can the trinity be explained as such...a man is a father, a son and a husband, i.e. one person with three distinct roles? Please give simple examples such as this followed by any pertinent scripture.

Except for the reference in Matthew 3:11, the term "threshingfloor" is found only in the Old Testament. Its use there indicates there is a particular significance in a "threshingfloor". 2 Samuel 24 tells of King David buying a threshingfloor, to build an altar on it. Why a "threshingfloor" and not a field or some other structure? I believe God has a purpose in every word in His Bible. What's the significance in this usage?

Please explain the thirty minute silence in Heaven of Revelation 8:1.

I am searching for lessons on the synoptic gospels. I hope to answer the following questions: 1. Why are three so similar and John is not 2. What specific stories are told in Matthew, Luke and Mark and how are they similar and how are they different? 3. Why are Matthew, Mark and Luke referred to as the synoptic gospels? Can you provide some resources to answer my questions?

When a man dies, where does the spirit go? If the "spirit" of man is the one that gives the believer the knowledge of God, then does the "spirit" of an unbelieving man have knowledge of God?

Please define and explain the characteristics of the soul and the spirit of man.

How do you describe one's sin nature? How do we inherit this nature? In what ways are we sinners?
