That you need to be a Christian to know right from wrong when Christians seem to do wrong an awful lot.
That sex is something sacred and special reserved for just your spouse.
That sex and pleasure is bad, and war and violence is good
You don't have to be a Christian to know "right from wrong" - but being a Christian allows the Holy Spirit to live and work within you to do God's will. Being a Christian is not about being "good".
Sex is sacred and special reserved for your spouse. Agreed
Sex and pleasure are not bad. They are gifts from God to be enjoyed between a married male and female.
War and violence are acceptable at God's command.
