Midrasch zu Jeschijahu 64:4

R Ami said again: "Rain falls only for the sake of those who have faith in God; as it is said (Ps. 85, 12) Truth springeth out of the earth and righteousness hath looked down from heaven." R. Jochanan said: "He who makes himself righteous (strives for righteousness) [here] below, is judged righteously (strictly) above; as it is said: "Truth springeth out of the earth and righteousness hath looked down from heaven." R. Chiya b. Abin, in the name of R. Huna, made the same inference from the following (Ps. 90, 11) Which is like the fear of thee. Resh Lakish made the inference from the following (Is 64, 4) Thou acceptest him that joyfully worked righteousness, those that remembered Thee in Thy ways; behold, thou wast wroth, and we sinned upon them have we stayed of old, that we might be saved?
