I Corinthians 13:6

I was but a little displeased, and they helped forward the affliction.

Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.

Love is not premeditated, it is spontaneous, i.e., it bursts up in extraordinary ways. There is nothing of mathematical certainty in Paul's category of love.

We cannot say - "Now I am going to think no evil; I am going to believe all things." The characteristic of love is spontaneity. We do not set the statements of Jesus in front of us as a standard; but when His Spirit is having His way with us, we live according to His standard without knowing it, and on looking back we are amazed at the disinterestedness of a particular emotion, which is the evidence that the spontaneity of real love was there. In everything to do with the life of God in us, its nature is only discerned when it is past.
