Personally, I don't like that kind of thing (I think it defeats the purpose) because it is written in the OT that we ought not to mark our body...and in Matthew 5:17-20 I find the teaching of our Lord that not one jot or tittle shall pass away from the law until heaven and earth pass away and all is fulfilled (including heaven and earth passing away).
I do believe that believers under the New Covenant ought to have the law written on our hearts and in our minds (Hebrews 8:8-10, Hebrews 10:16, Romans 8:7, Romans 8:4, 1 John 5:3, 2 John 1:6).
