3 For the time will come when they will not endure sound doctrine; but wanting to have their ears tickled, they will accumulate for themselves teachers in accordance to their own desires, 4 and will turn away their ears from the truth and will turn aside to myths.
I've always taken these verses to be referring to non-Christians; but I see more and more that we, as believers, are also just looking to get our ears tickled. We gauge our closeness to God on our emotions and the feelings we experience. We only listen to the preachers who say what we want to hear. I think there is a more level-headed way to approach things that takes the emphasis off of what we feel and puts it where it should be: God's glory.
The next verse tells us to be sober in all things and endure hardship. This doesn't really tie into what I'm talking about here but I like it--a lot--so I'm gonna give my two cents on it anyway.
Be sober in all things and endure hardship. It's gonna be hard, it isn't gonna be fair; but don't let your emotions get the best of you. Be sober in all things and endure hardship.
It's like I tell the boys I coach, and sometimes the girls: "Quit crying and suck it up."
