I would like to first ask for prayer for my 18 year old daughter Rebecca who has been drifting away from her walk with God over the last few years....since around 10th grade. She was raised in a Christian home and was baptized at age 14. The influences of high school friends, social media, movies, music and the general anti Christian culture have really changed her. She no longer believes the Bible is the 100 percent the word of God and that everything it says is final authority. She influenced by liberal college professors who hate religion and delight in "debunking" the bible. So yes, she can use prayer to return to Christ. I need advice however on how to back up my views on waiting till marriage for sex. My daughter sees no reason to wait for marriage. She thinks its ridiculous. The world says its nothing to be ashamed of and its natural and if you are in love, its normal. I tell her God created sex as an expression of love between married couples and for having children. But she does not accept that she should live her life according to a book...written by men. How do i seriously present to her why i believe she should wait until marriage if she isn't convinced of the truth of the bible? I know shes 18 but i still want to have a strong case for why i believe in saving sex for marriage. Im really concerned about her. How have you presented your feelings on this issue to your teens...especially when they challenge you on your commitment to biblical authority? Thanks!
