"you can tell how well a tree has been cared for by its fruits"<quoted text>
Excuse me? Are you really saying those two passages are saying the same thing, not even close if you ask me.
"you will know them by their fruits"
"if you forgive someone who has wronged you, your sins will be forgiven when you pray"
"forgive us our trespasses as we forgive those who have trespassed against us"
