"'God’s providence could allow a bird to serve as a sign and a reminder to us of the presence of our loved ones and their kindness and care for us,' said Fr. Kirby." "This is an evil generation: they seek a sign; and there shall no sign be given it, but the sign of Jonas the prophet" (Luke 11:29). It is actually evil looking for heavenly signs, especially those that confirm people in the error of their ways. "I will follow the Bible but if God sends a sign otherwise, I will not obey that" is exactly what many Christians live by in one form or another. They place signs above the Bible as if God contradicts His Word through signs. Looking for signs and attributing them to Heaven sent messages opens up the allowance of Satan to step in. Signs are to further confirm the Word of God (Mark 16:17).
