Book excerpt: Answers one of the biggest barriers to belief. Christians are increasingly seen as outdated, restrictive and judgmental when it comes to sex before marriage, cohabitation and homosexuality. In fact for many people, this issue is one of the biggest barriers for them considering Christianity. Sam Allberry, author of many books including Is God Anti-gay sets out God's good design for the expression of human sexuality, showing that God himself is love and that only he can satisfy our deepest desires. It is a great reminder of the Bible's positive blueprint for love, sex and marriage and ideal for giving away to people who may see this as a stumbling block for belief.
