Has man's study and involvement in the debate of origins benefited Christianity? Have such studies brought people to salvation in Christ? Have such studies helped mature believers? Have such studies, in the end, glorified God? Or have these studies benefited man's understanding of scripture, theology, or the nature of God? What have been the practical benefits of the development of Creation theories? Or I could phrase it, what has been the 'fruit' of such labors?
And if this study of Creationism has benefited Christendom, has it done so more than had the efforts been otherwise placed. If those who study/debate Creationism/Evolution were to spend their time in other arenas, such as philosophy, history, theology, evangelism, missions, etc., would there be greater benefit to Christianity? Would God be more glorified? Is the benefit sufficient for the work required to make a difference? And is other work more beneficial to the cause of Christ?
This would generally apply to any who would call themselves Christian (though perhaps any of religious/theistic-belief could answer). Your actual position on the Creation/Evolution debate is irrelevant. The question is more "what is the spiritual benefit of your studies", not what is the scientific benefit.
