Dr. Helen Roseveare, missionary to Zaire, told the following story. "A mother at our mission station died after giving birth to a premature baby. We tried to improvise an incubator to keep the infant alive, but the only hot water bottle we had was beyond repair. So we asked the children to pray for the baby and for her sister. One of the girls responded. 'Dear God, please send a hot water bottle today. Tomorrow will be too late because by then the baby will be dead. And dear Lord, send a doll for the sister so she won't feel so lonely.' That afternoon a large package arrived from England. The children watched eagerly as we opened it. Much to their surprise, under some clothing was a hot water bottle! Immediately the girl who had prayed so earnestly started to dig deeper, exclaiming, 'If God sent that, I'm sure He also sent a doll!' And she was right! The heavenly Father knew in advance of that child's sincere requests, and 5 months earlier He had led a ladies' group to include both of those specific articles."
1Jo 5:14 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
1Jo 5:15 And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
