Jesus' real disciples

At Matthew 28:19-20--- Clearly shows who the real teachers and real disciples are. The ones taking the lead-teach every single teaching Jesus gave without fail. The real disciples learn and apply every single teaching Jesus gave without fail.
Here is a super important one every real disciple knows by heart--Matthew 6:33- Keep on seeking- FIRST- the kingdom and his ( YHWH(Jehovah) righteousness and all these things will be added( sustenance, covering, spirituality) Matt 6)

Are you taught that super important teaching?
