“....Is it also pointless/sinful to ask angelssuch as the angel Jesus says is assigned to each of usto pray for or assist us in any way?....”
Why would any individual pray to anyone other than Jesus? Common sense tells us He’s the King and we have direct access to Him at any time...and He has asked we make our requests known to HIM.
It would seem people who have a need to go elsewhere aren’t comfortable enough taking to Jesus. I think it has much to do with whatever their relationship is with Him....maybe their too distant from Him...maybe they haven’t spent enough time with Him to build the ralationship of trust....but it likely falls on their relationship with Him and where that is.
Did your mother ever pray for you in her life? Should she not bother, since Jesus does everything?
Would you ASK your guardian angel for any kind of assistance?
If not, why not?
If not, then wasn’t it pointless for God to appoint an angel specially responsible for you?
