The doctrine of subsequence

[Luke]

2 Peter 1:4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.

This verse is one that screams a second work. Notice that the scripture is to those who have escaped the corruption that is in the world and to them have been given exceeding great and precious promises that these they MIGHT (or are enabled) be partakers of the divine nature. The passage clearly shows that though they are saved they still retain their carnal nature but because they are saved they have been given promises that are not given to the lost and by these promises they can partake of the divine nature. This shows that before one can partake of the divine nature they must first be saved but it also shows they don't partake of the divine nature at the point of salvation.
