Puzzled about How Money Should Be Handled?

1 Corinthians 16: 1-4 (NIV)

1 Now about the collection for the Lord’s people: Do what I told the Galatian churches to do.

2 On the first day of every week, each one of you should set aside a sum of money in keeping with your income, saving it up, so that when I come no collections will have to be made.

3 Then, when I arrive, I will give letters of introduction to the men you approve and send them with your gift to Jerusalem.

4 If it seems advisable for me to go also, they will accompany me.
