UK vs. US English in the NIV Bible

I have excitedly begun reading through the Bible for 2008 with three sisters...and for my first time in the UK-English version of the New International Version. I honestly didn't know there was one until moving here. I think it's fun, having gone to a British elementary school for "prep" (kindergarten) through 6th grade, and now living here in England.

Words I have come across so far that are different:

no-one, realise, sympathise (from Job; vs. no one, realize, sympathize)

practise, Counsellor, for ever (from Isaiah, vs. practice, Counselor, forever)

favouritism (from Romans, vs. favoritism)

mouldy (from Joshua, vs. moldy)

Some of my favorite parts read for January 1st-7th:

In the gospel a righteousness FROM GOD is revealed, a righteousness that is BY FAITH from first to last.
Romans 1:17

No one will be able to stand up against you all the days of your life. As I was with Moses, so I will be with you; I will never leave you nor forsake you. Be strong and courageous, because you will lead...
Joshua 1:5-6

His delight is in the law of the LORD, and on his law he meditates day and night.
Psalm 1:2

Serve the LORD with fear and rejoice with trembling...Blessed are all who take refuge in him.
Psalm 2:11, 12b

Shall we accept good from God, and not trouble?
Job 2:10

The arrogance of man will be brought low and the pride of men humbled; the LORD alone will be exalted in that day, and the idols will totally disappear.
Isaiah 2:17-18 (how I long for this day! My pride crushed and gotten rid of - good riddance! The Lord reigns over all; I can't wait until it's final)

He will save his people from their sins...."Immanuel"—which means, "God with us."
Matthew 1:21, 23

When they saw the star, they were overjoyed.
Matthew 2:10
