Joseph had lived in Egypt for about thirteen years when he was brought to Pharaoh's attention. During that time, he had learned the Egyptian language. I don't know how far he had assimilated into the culture.
But when he was taken to see Pharaoh, he transformed into an Egyptian in all outward respects. They cut his long, curly hair and beard and changed his clothes.
Consider how a typical ancient Hebrew dressed:
Now look at Egyptian clothing from ancient times:
Joseph had to accept major changes to fulfill the destiny God placed upon him. He even accepted an Egyptian name that spoke more powerfully of God's involvement in his life than "Joseph" (may God add more sons to me): Zaphenath-Paneah, or "God speaks and He lives."
We tend to equate our faith with our cultural trappings, but that is far from the case. If Joseph had been unwilling to adapt to a different culture, he wouldn't have accomplished God's purpose in his life.
Father Damien ministered in a leper colony - and in time, himself became a leper.
I'm a nursing home resident - and can minister to other residents in a way the staff cannot.
Don't be afraid of joining the community where you are place. God has a purpose for you there.
