There's nothing to interpret, those verses are straight forward. They apply to those who preach a false gospel, you know those guys in the pulpit, who just add a word here and remove a word there from Gods Word.Again I'm needing to teach you.
11:14 And no wonder, for even Satan disguises himself as an angel of light. 11:15 Therefore it is not surprising his servants also disguise themselves as servants of righteousness, whose end will correspond to their actions 2 Co 11:14–15.

Gods elect are not fooled by them, but everyone else is.
Matt 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
As you can see Gods Word confirms that's it's impossible to deceive His elect, so Satan can disguise Himself as an Angel of light al He likes but He will never deceive us.
