Here again, we see another author of the New Testament urging us toward "perfection". As we discussed about 2 months ago, we must not look at these statements and throw our hands up in despair. We must really aim to be perfect, but when we fall, immediately dust ourselves off and go forward in the confidence of God's grace that covers our sins.
Likewise, we must really aim to be of a 'like mind' and at peace in our community. It's not going to just happen. We need to always put the effort to maintain our unity. When something breaches that (which will, of course, happen), we must mend that breach, and continue striving for a 'like mind'.
You’ve got your methods
I’m done with trying to guess all your moves
I’m going where you want me to go
I’ve got nothing left to lose
Now I don’t wanna suffer
But that’s in fact the nature of the beast
If you want to get to higher ground
You got to get there on your knees
