What is the Biblical basis for Christians having a "personal relationship" with Jesus/God?

Previous questions have already explored various facets of the notion of having a "personal relationship" with Jesus/God, such as: - https://christianity.stackexchange.com/q/470 - https://christianity.stackexchange.com/q/7703/61679 - https://christianity.stackexchange.com/q/44771/61679 However, a question on the Biblical basis for this concept is missing. Do Christians who claim to have a "personal relationship" with Jesus/God believe that this concept has a Biblical basis, and if so, what is it? Does the Bible explicitly outline all the elements of a "personal relationship"? Is there anything close to a canonical list of attributes that define what it means to have a "personal relationship" with Jesus/God, with each attribute supported through exegesis of one or more Biblical passages?
