what does this mean?

Galatians 3

26 For you are all children of God through faith in Christ Jesus.

27 And all who have been united with Christ in baptism have put on Christ,

        like putting on new clothes.

28 There is no longer Jew or Gentile,

        slave or free,

        male and female.

For you are all one in Christ Jesus.

29 And now that you belong to Christ,

        you are the true children of Abraham.

You are his heirs,

     and God's promise to Abraham belongs to you.



Here's some key phrases here...

     "...children of God..."

     "...put on Christ..."

     "...all one in Christ..."


What does that mean to each of us?

And what does that mean to the world we live in today?
