They may care about an agenda. The Bible does not directly address interracial adoption, but the entire Bible is written about adoption. Many people longing to be parents, like yourselves, give everything they have to adopt an orphaned child into their home. You have incredible love to give, and there is a child who needs incredible love. Ethnic backgrounds are all fully loved by God.
Adoption is a wonderful act of love and kindness.
Many people are capable of having children, but it takes an amazing love to invite somebody else's child into your home. God bless you, and don't be discouraged by those who can't see beyond themselves. I know the Bible tells me not to be anxious, but I can't seem to stop. I'm glad you are seeking help, rather than wishing away your problem. First, let me say that the root of anxiety is fear.
