(Rolling my eyes)
(Oh sure, NO preacher, no pastor in his pulpit, no priest, EVER gives 'EARTHLY' examples...In fact, we 'ALL KNOW' Jesus NEVER cites any 'EARTHLY' examples in His parables...or the Bible NEVER uses common elements of the earth...nature...wildlife...harvesting food...the weather/climate...as illustrations or word pix /sarc)
(Oh, Lord, spare me from such drivel)
You WILL notice, that Christmas carols...and hymns/praise songs...the OTHER examples I gave...is hardly only an "earthly" application...are they? Well, I guess, in one sense, you can't get any more "earthly" than the Son of God's condescension with His incarnation into dirty diapers.
(But hey, if baby Jesus' dirty diapers are just too overwhelmingly "earthly" for ya, just move on into your transcendent sphere above)
The Lord says: "These people come near to me with their mouth and honor me with their lips, but their hearts are far from me. Their worship of me is based on merely human rules they have been taught. Isaiah 29:13
These people honor me with their lips, but their hearts are far from me. They worship me in vain; their teachings are merely human rules". Matt 15:8,9
