Add the second verse of Matt 7 "2 For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you,"
Using the Word of God is the proper way to judge. All will be judged by it. It is the 'same measure' by which I am/will be judged.
you are taking God's job there!
Typical for one with no regard for His Word, if I use God's Word to judge, He has already spoken, your complaint is with Him. In this case it apparently is in conflict with your 'common sense'.
