St. Monica prayed for 17 years that her son, Augustine would convert to Christianity. She kept believing in her son, like the bible quote. She had children that didn't survive past infancy, but she kept believing that God would provide for her and care for her.
Matthew 15, King James Version (KJV) "Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour." This represents St. Monica and her great faith heals people.
Hebrews 11, King James Version (KJV) "1 Now faith is the substance of things hoped for, the evidence of things not seen." This quote means that as long as you believe in God, you don't need to point out any other evidence.
