Dearest 6of9... you make a good point... and may you have peace!
However, may I ask you... is not the eating of swine and shellfish under the same 'law' as not having one's body pierced? And yet, do not those who might be 'stumbled' eat such things?
Dear one, it is no longer the OUTSIDE of the 'dish' that my Father and my Lord are concerned with, and in truth, it never really was. For it is the INSIDE of the cup that must be cleansed. If then, we run around looking at the outward appearance of others, and attempt to determine their spirituality and righteousness on what we see with our eyes, are we not running the same risk as did the Pharisees, of whom my Lord stated looked themselves "like whitewashed graves", but INSIDE were "full of deadmen's bones"?
My point, dear 6, is that "all things are clean to him that IS clean", and all things are unclean... to him that is unclean.
If someone has a body piercing, a tatoo, or some other 'marking' on their flesh, such will not prevent them from entering into the kingdom of my Lord. It is, instead, the 'markings' on the 'heart', 'forehead'... or 'hand'... and whose 'mark' it IS... that determine such entry.
Ezekiel 9:4
Revelation 3:12
Revelation 7:3
Revelation 13:16, 17
Revelation 14:9
For it is NOT the physical 'markings' of a man... but the SPIRITUAL 'markings'... that matter.
I bid you peace... and commend you for your love in noting the possible stumbling block. For indeed, as you said, while all things ARE lawful... not all things are advantageous.
I am your servant and a slave of Christ,
SJ
