Question:Would you recommend specific passages that I can use for a girl who still harbors pain, anger, resentment, but who is looking for acceptance and love? I have tried to express love and acceptance to her. I think she believes me but doesn't believe that God loves her. What can I do?
You know this young woman much better than I do. Overall, what you are doing is giving the best opening to Gospel. Her observation of God in your life will make a lasting impact. When you can, introduce her to Scriptures that help her decide what to do in various situations. Since Peter tells us, "As His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue" (II Peter 1:3), we know there are solutions to everyday problems, common and uncommon, within the pages of the Bible. When a person sees that God has their best interest at heart and helps them through life, then that too makes an impact in their life.
If I can recommend anything, it is to help her learn the power of forgiveness. Perhaps you can find some of the psalms where David speaks of forgiveness, one of Jesus' stories about forgiveness, or Joseph's story that includes his forgiveness of his brothers and ask if you might read them to her. Then just ask a question or two to see if she understood the story. Many times a simple story makes a greater impact than a detailed study. You can do the same on other themes, such as God's love and mercy toward mankind.
