Wednesday Night Services

How can we determine that a word seemingly so very contrary to others we have heard is or is not from God? After some very positive words from the Lord given to Zechariah to encourage the returnees who came back to Judah and Jerusalem, here comes this word prophesying a coming destruction. How would you take this shift if you were on of the Jews in Jerusalem hearing this? We also see the context for the prophetic word about Judas receiving 30 pieces of silver to betray Jesus.
