I agree that there is none good. Jesus told the rich man that no one is good but God alone. (Matt 19:17, Mark 10:18, Luke 18:19)
However, Jesus did use the word good to describe His creation. He stated that our heavenly Father makes His sun shine on the bad and the good. (Matt 5:45) He also stated that a good person brings forth good out of a store of goodness, but an evil person brings forth evil out of a store of evil. (Matt 12:35, Luke 6:45) And in the parable of the talents, Jesus mentioned good and faithful servants. (Matt 24:21,23)
Just so, my Mom was a good and faithful Christian.
