Sh'mini Torah Portion-"Are We Offering Holy Fire, Or Strange Fire?"

This Torah Portion cut right to my own heart when it comes to what is 'strange fire" and what are believers in Yahshua (Jesus) doing that could be considered "strange fire"? I also incl myself in this, as we have to all examine ourselves, in prayer and ask "Father, am I bringing "strange fire" to Your altar"?
