The weaker a person is, the more capable they are.

My beloved sister, please understand that if someone wants to love Jesus, to be a victim of His love, then the weaker, more devoid of desires and virtues they are, the more capable they are for the action of this consuming and transforming Love... A mere desire to be a victim is enough, but one must agree to remain poor and powerless, and that is difficult... (...) Trust, and nothing but trust should lead us to Love...

(Therese of the Child Jesus and the Holy Face, letter 197, to Sister Mary of the Most Sacred Heart, September 17, 1896)
