As a disciple is called to come out from the 'beast' (beast in the prophetic apocalyptic sense) as it is an empire continuing on from the Roman Empire and still has the same attitude against God and His Truth and since that separation does not deny the need to trade with the opposing empires it seemed sensible to me to produce tools for trade with any empire or beast or apocalyptic Babylon the Great. To allow those obeying the call to come out and be separate I helped to ensure there are tools for trade and one such tool is an electronic invoice and business document standard. So the call is there to be separate and the commands are there to trade with worldly wealth to increase it for returning a dividend to Christ when He wants it and another command to help lift the burdens we impose so a standard for trade across boundaries made sense. So promotion of trade using invoices that can be read anywhere by electronic modern methods is really part of my personal discipleship mission statement. (End result to date: ISO/IEC 19845:2015.)
