This is a tough process. Please pray for us

I have been planning on adopting my unborn bio-niece. I have been having a difficult time though. I have not been hearing from my sister who has assured me that this is her plan. She has been through a lot and I know this was a hard choice to reach. I have been there for her. She was in jail (due in part to an addiction, but I think in large part God was trying to keep the baby healthy). I'm really looking forward to adopting and raising this child. Our home study was done today. I know I have to trust God with everything. I just get discouraged and worried when I dont hear from my sister.Also I worry at times that she is being manipulative. She said she found God and was saved while she was in jail. I hope you all will pray for her. I do love her but this process has been hard. We had a home study done to day and are using a lot of resources for the adoption. Please just pray for God's will in our life. My husband and I have four children-who are all blessings and this little girl would be our second daughter. I know God has a plan for her life and I just need to trust him-not my own knowledge or understanding.
