Our knowledge is by the ministry of the Spirit, through the Word, but even that is full and complete, so that we may still learn faith and lean on God rather than our understanding:
1 Corinthians 13:12 (NASB)
12 For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known.
Yet you seem sure of your position. So sure that you not only propose to judge your brothers, but to teach your brothers to do the same (but according to your standards of measure). Are you willing to stand/fall before the Lord by the accuracy of your position?
Matthew 7:1-5 (NASB)
1 “Do not judge so that you will not be judged.
2 For in the way you judge, you will be judged; and by your standard of measure, it will be measured to you.
3 Why do you look at the speck that is in your brother’s eye, but do not notice the log that is in your own eye?
4 Or how can you say to your brother, ‘Let me take the speck out of your eye,’ and behold, the log is in your own eye?
5 You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother’s eye.
