YOu know God will see you through. One day, or minute at a time. Even though you are unsure of your walk, dont worry. All you need to do is ask the lord to forgive you for not walking with him. Tell him you need him to carry you through all the hard times. See Even when we are NOT faithful to the lord, he is to us because he LOVES us unconditionally so much. He is always there, no matter what. The bible says, Children are a GIFT from god. It is true.Focus on your walk with the lord and your baby. Dont worry about those friends. They will come and go, but God is always faithful to his kids. In the book of matthew it says that we are the lords responsibilty. Are not two sparrows sold for a small coin? Yet not one of them falls to the ground without your Father's knowledge. ... So do not be afraid; you are worth more than many sparrows." Matthew 10:29-31.
Just remember, Jeremiah 29:11 says; He knows the plans for your life, to give you a hope and a future.
