Back in the 1970s I met a poor Indian woman who lived in the woods;she had never been allowed to go to school so when God spoke to her we knew it was true because she could not read the Bible. She frequently would quote scriptures she had neither heard nor read and her expeiernce in churches was limited.
She told us a story of when she was 3 years old. She knew she was the 2nd child in the family and that her older brother had been born and cried continuously, but he died. She told her mother repeatedly that she could hear a baby crying down by the creek which bordered on the far end of the property. This went on for several years.
Later as an adult she learned her father had killed the baby boy and dumped his body in the creek. Genesis 4:10 tells of God hearing the blood of the slain Abel crying from the ground.
Genesis 4:8-10 New International Version (NIV) 8 Now Cain said to his brother Abel, “Let’s go out to the field.”[a] While they were in the field, Cain attacked his brother Abel and killed him.
9 Then the LORD said to Cain, “Where is your brother Abel?”
“I don’t know,” he replied. “Am I my brother’s keeper?”
10 The LORD said, “What have you done? Listen! Your brother’s blood cries out to me from the ground.
My Indian friend had no knowledge of the scripture, but she certainly could hear her brother’s cries. That is why we can say the “little children” are in the Kingdom of Heaven. They have access to truth from the other side of the grave.
But Jesus said, “Let the little children come to Me, and do not forbid them; for of such is the kingdom of heaven.”
