For you are a people holy to the LORD your God.
The LORD your God has chosen you out of all the peoples
on the face of the earth
to be his people,
his treasured possession.
Deuteronomy 7:6 (New International Version)
Holy means "set apart". The Word of the Lord just tells us we've been set apart out of many (6,805,700,000 people in the world according to US Census Bureau) whoever you are, no matter where you're from, whatever your background is,
You are and will always be HIS!
And and not just HIS but one that is TREASURED (person greatly valued or highly prized according to Dictionary.com)
When you experience, rejection or the feeling of being unwanted, remember this verse...
You will always have HIM!
