John PiperFaith stands or falls on the truth that the future with God is more satisfying than the one promised by sin. Where this truth is embraced and God is cherished above all, the power of sin is broken. The power of sin is the power of deceit. Sin has power through promising a false future. In temptation sin comes to us and says: "The future with God on his narrow way is hard and unhappy, but the way I promise is pleasant and satisfying." The power of sin is in the power of this lie.

Those with same-sex attraction glorify Christ through sexual abstinence and through the enrichment of significant Christ-exalting relationships in other ways.
John PiperBeing infinite, God is inexhaustibly interesting. It is therefore impossible that God be boring.
