There is a generation of smart phone users who have never seen this kind of a dial.
It is an obsolete “dinosaur” from a by-gone day.
So much has changed & so rapidly in the area of telephone technology!
Of course, there is One Who thankfully is completely unchanging: The Lord Jesus Christ!
Hebrews 13:8:
“Jesus Christ is the same yesterday and today, yes and forever.”
Ponder the tremendous benefits to you since your Lord & Saviour is unchanging & never obsolete!
