The reference was, obviously (I made a precise reference earlier in my posts to you) to 1 Timothy 1:19-20, about the loss of faith.
Gill's commentary is either dull or obfuscatory, since he ignores the fact that Christ urges His followers to do works beyond obligation, i.e. charitable work, and the fact that the parable is in response to a request to increase faith.
Of course I did notice that you've backtracked from the early comment that the "seed of faith" comes from God. At the very least you have not explain your position. Would you care to explain what is faith and where it comes from?
