John 14:21-23 KJV
21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him. 22 Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? 23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
The passage in John 14:21-23 presents a clear assurance of both the manifestation of Jesus to those who love Him and the promise that the Father and the Son will establish their abode with faithful believers. However, the precise nature of this manifestation and the implications of the Father and the Son making their abode with believers remain unspecified in the text. Essentially, the passage leaves unanswered questions about what this manifestation entails and what practical implications arise when the Father and the Son choose to dwell with the believer, promises that seem deliberately worded in metaphorical language. Put simply, the passage doesn't explicitly detail the expected outcomes in concrete, practical, and non-allegorical terms.
How, in concrete and practical terms, do the Father and the Son manifest themselves to Christians based on the promises laid out in this passage?
Note: the question was inspired by the answer to What is the success criterion for the task of 'seeking God' in Christianity?.
