Atheists cannot quote the bible to "defeat" a Christian's argument because an atheist does not have the gift of the Holy Spirit and, therefore, becomes confused by what the text means because they are not spiritually perceptive. God's spirit speaks to Christians and what has happened to you is that a Christian has answered you but due to your limited understanding of God and non-existent spiritual perceptiveness you could not glean the meaning of their answer. You simply have not understood and you use other passages - out of context - to try and justify your own point of view. You have no recognition of God's spirit and won't until you accept Jesus as your lord and saviour.

Good luck with that.
