Is it wrong to use swordsmanship to strengthen the bond between my Creator and myself?

I have recently discovered the unconditional love the creator has bestowed upon me. I want to supplement my journey with the Almighty with a disciplined, and formal martial art. I have been looking at Iaido as one of those arts, and I am wondering is it wrong to study swordsmanship as a Christian? From what I can tell, there are no religious connotations to Iaido, and the mysticism that is inherent in some forms of marital arts is not present here. Please give me some advice while I walk this difficult path.
