Well for a little lesson:
Mt.28:20 "Teaching them to OBSERVE ALL things I have commanded..."
Mt. 7:24-27....therefor whosoever heareth these sayings of mine and DOETH them, I will liken him unto a wise man...........and everyone that heareth these sayings of mine and DOETH THEM NOT I will liken him unto a foolish man.
1Tim. 6:3....if any man teach other wise and consent NOT to the wholesome WORDS OF OUR LORD JESUS CHRIST......he is proud, knowing nothing.
Jn. 13:4-17 just the highlights:
Jesus takes literal water in a literal pan and literally washes the disciples literal feet.
Tells Peter if he does not wash his feet 'thou hast NO part with me'
v.12..................KNOW ye what I have done unto you?
v. 13 Ye call me Lord and Master and ye say well for so I am.
v.14 If I then be your Lord and master have washed your feet ye ALSO OUGHT to wash one another's feet.
15. I have given you an EXAMPLE that ye should DO as I have DONE to you.
v.17 If ye know these things happy are ye if ye DO them.
Your choice. Be foolish if you want to I will be wise and DO what Jesus DID and commanded.
