i think i see Peter's comment radically misused sometimes . . .
that is, when people affirm the grace and freedom we have in Christ, and make reference to something in Romans or Galatians to support it, out come the accusations of "twisting" and "misunderstanding" what Paul says to us.
The 'Rock' of CHRIST have spoken 'this' and 'testified' according to his own 'epistle' to the church, for as 'a reminder' and 'a stir up of memory', in order for the church, even today, in 'spiritual taught sound doctrine lesson', live to 'distinguish between the spirit of error and the spirit of truth' and not 'receive everything that comes our way, given initially of still CHRIST of the New Covenant/Testament.
GOD bless all in the name of LORD JESUS CHRIST.
