There are many interpretations of that line, and without the context it is in it is difficult to see which one is correct.

Here's one:

"Jesus' statement highlights the principle that salvation is a gift from God, not earned through good deeds or accumulated wealth. It emphasizes the need for humility and faith, rather than relying on material possessions or social standing."

Forgive me, but as a non religious person the bible is no authority for or of me so if that's the best you have I find we're at an impasse.

I was like, surely not someone quoting al-A'raf (Qur'an 7:40) on the orange site but it turns out it is the New Testament (Luke 18:25).
