self-abuse will always drag us down, no matter the genre - when we are convicted of doing something
wrong and it affects our daily lives, and especially the lives of others, then of course we know that our
Saviour wants/demands so much better from/for us...
acting upon conviction is a whole other matter, it will show us our mettle and where we stand in our
wanting to please and obey our Lord...it's a personal scale that only we can read and do something
about with His help...
I can't say that 'martial-arts' is a bad thing, especially if one can use such to help bring others to Christ..
but, if it is a 'vain' endeavor, simply done for self-gratification, then it would be useless, especially if you
believe that you belong to Jesus and that everything that you do is to help and show others where His saving
Grace can lead to, and this should be obvious in everything we do and say because our lives are all about
Loving and Serving Him...
ACTS 24:16.
And herein do I exercise myself, to have always a conscience void of offence toward God, and toward men.
JAMES 4:17.
Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
the Scriptures plainly speak in many verses about your dilemma...
it always goes back to the basics of Loving God with all of our hearts, souls, and minds...
I understand your point. But it seems we are led to have absolutely nothing in our lives as if our "metal" is strong in Christ, we do nothing but serve Christ. So all things will go if our metal is strong. Hobbies, jobs, entertainment. Unless it's a thing that revolves around god or godly purposes (godly music, godly works). Not because we're told to, but because our metal tells us to. And if we ignore, then. God didn't know us, and we are fallen in judgement? So anything we do that our metal says is not helpful, godly or growing up is not in Christ's will. This eventually leads us unavoidably to be travelling or static ish priest like people without the title. Depending on our personal conscience and alarms scale etc.
So you can do any hobby but if your scale doesn't tell you it's ungodly, your still not in Christ, you just don't know it as much. Thoughts?
