The parable of the sower indicates 2 seeds that definitely weren't true believers, 1 seed that might be a weak believer, and only one seed that definitely was a true believer.
That is the danger of "easy believism." Some seem to receive the word with joy, but then they fall away. If we've told THOSE peoplE that they're "eternally secure," then we've done them a disservice. Apparently, they're in desperate need of initial salvation. And here they are thinking they've got a fire insurance policy.
The best PRACTICAL sign of eternal security is eternal perseverence.
ahhh The troubles of Arminians...If it is man that saves maybe he screwed up...then someone will burn in hell because of me...
