WE are all ONE in union with Christ Jesus

So there is no difference between Jews and Gentiles, between slaves and free people, between men and women; WE are all ONE in union with Christ Jesus. AND If WE belong to Christ, then WE are the descendants of Abraham and WILL RECIEVE WHAT GOD HAD PROMISED TO ABRAHAM. Gal. 3:28-29GNT HOW DOES IT FEEL TO BE AN HEIR TO A VERY WEALTHY MAN?
