...it only matters where you are going.
Regardless of your ethnic, culture, or family background.
If you are going to heaven, you will have the Spirit, either now and forever, or it will come to renew you before you die. Look for the evidence of the Spirit in your life.
Howwever, your background can help your ministry (and every Christian has a ministry in some form or another) by enabling you you relate to a certain group of people. Sometimes your background is preparation for living outside your comfort zone, and then it is likely that you will be going into a foreign mission ground (which could be a local culture that is different from your own).
