In Srimad-Bhagavatam (9.4.68), the Lord says:
sadhavo hridayam mahyam
sadhunam hridayam tv aham
mad-anyat te na jananti
naham tebhyo manag api
"The devotees are always in My heart, and I am always in the hearts of the devotees. The devotee does not know anything beyond Me, and I also cannot forget the devotee. There is a very intimate relationship between Me and the pure devotees. Pure devotees in full knowledge are never out of spiritual touch, and therefore they are very much dear to Me."
