My heart goes out to you and all single Mothers, trying to fill both roles in this modern age... i wish that I lived close to you, because you would never feel alone. Im not speaking from a physical or relationship perspective either... YOU are absolutely right to feel like you do, because people as 'The Church' Dont live as GOD intended. In biblical times, People lived in societies that cared for one another- ate together, carried each others burdens, etc. (and in undeveloped countries they largely still do), so a person was never truly alone. GOD continuously speaks on caring for widows and orphans, its pretty clear as to why.
I was on a mission in the Caribbean and during my travels I was Blessed to stay a few Days with a Family in a Mennonite Community, GOD blessed me to see his perfect plan in action, these People Love each other, share each others burdens, Build with each, raise each others Children, Edify each other and so on.
Its Sad that people can memorize scripture, but struggle so hard to apply it.
Love you, sister. Know that you are definitely not alone, in these End times 😊❤. You and your children are in my prayers.
