Paul told Timothy to "pursue righteousness, faith, love and peace" (notice this next qualifier) "with those who call on The Lord out of a pure heart" (2Timothy 2:22). Attempting to pursue peace with those who use The Lord as a cover and are not sincere often results in anguish, turmoil, arguments and anything but peace. Paul tells the believers in Rome to avoid such people (Romans 16:17-20).
Arguing scripture leads to strife. Discussing scripture leads to life.
