Ezra saw intermarriage as a compromise in people's faith. Do people today make other compromises that have the same impact on their faith?

While Ezra prayed and made confession, weeping and casting himself down before the house of God, a very great assembly of men, women, and children, gathered to him out of Israel; for the people wept bitterly.

~Ezra 10:1

 

It is very likely that they do.

Is it good for churches to receive help - financial or otherwise - as the Jews did from Artaxerxes? What would be the dangers in such an approach?

I think it really depends.  You could be dealing with someone or something that is legitimate, or it could be a scam.

Which of Paul's arguments of Chapter 15 do you find most convincing? How does belief in an afterlife affect you?

If there is no resurrection of the dead, then not even Christ has been raised.  And if Christ has not been raised, our preaching is useless and so is your faith.

~I Corinthians 15:13-14

 

A lot of them are very convincing!  I am glad that God will be providing me with a new world of life with no harm or hardships after this life.

Of Paul's list of Spirtual Gifts, which are prominent in your church? Are Any overlooked? How do you fit in?

Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ.

~I Corinthians 12:12

 

I would say a lot of them, I'm not sure if any are overlooked or not.  I won't doubt if there really are a few that are though.
