Though we are saved by grace through faith in Christ alone, faith is never alone. As James says faith without works is dead. We have to work out our salvation with fear and trembling in whatever sphere of service in every sphere of life – in our jobs, family and society. That includes thinking Christianly about the ethical issues which face us and acting accordingly. Putting our faith into action will be costly but in so doing we will be bringing glory to Christ and having a disproportionate influence for good on those around us.
