The pressure to conform to the new group is so great. Yes, it will be hard and costly and gutsy and very lonely at times. You will be laughed at by some, mocked by others, and ignored by many. The temptation to quit or lie low or crawl into your shell will be very strong. Of course there will be changes.
Any new situation brings adjustments.
Your horizons will be broadened. Daniel's certainly were. Your lifestyle will change some. God expects you to relate to the culture in which He places you. Don't disobey the Word of God.
