"Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye?" - Matthew 7:3.
Whenever I see faults in my brother as something bigger than the fact of Christ in him, I am sinning. When my eye is single, it is full of light. In looking on my brother, my eye is single when I am seeing Christ in him, and only then. In God's sight that is all He sees, for ''by one offering He hath perfected forever them that are sanctified.'' My eye is evil when it is so fixed on faults and failings in my brother that they obscure my clear sight of Christ in him. And how easy it is to do that! It is the beam in my eye which hinders me from taking out the mote from my brother's eye. Motes are there (as also in me), but they are fiddling compared to my sin in making more of them than Christ in him. He is the apple of Christ's eye.
Let me therefore get my sin out of the way by confession and cleansing, and if led, by confession to my brother. Then let me renew my faith in the One within him who is busy conforming him to His perfect image. That is perfect love. It is not blindness concerning those motes, but it is clear-sighted faith and love. It surrounds the brother with love and contributes a living faith to the fact of a transforming work of the Spirit going on in him. That is the difference between criticism and discernment. Criticism sees the flesh or devil in a brother. It tears down and condemns. It has self-superiority at its roots. Discernment sees Christ in a brother. It edifies. It combines loving appreciation of the present with hope for the future.
