I appreciate what inspired the OPs question! A crucial point of how God reveals himself to a seeker (based on Hosea's book) is the need for *"**repentance and seeking God to help turn from unrighteousness**, then God's righteousness and mercy will be experienced, causing such a contrast in either group, or individual life, that it will be obvious to them that God has responded to their sincere seeking of him."*

The question now is ***how*** the Father and the Son reveal themselves to Christians (as based on the text quoted). Clearly, it is a personal revelation to the individual. Nowhere does Jesus speak of any 'group' experience. The language is always about an individual who comes to discover the mystery of God and Christ indwelling the believer.

Yet enough is said by Jesus to show what practical steps the individual must take if they are to have this experience: (1) Knowing Christ's commands. (2) Keeping Christ's commands. (2) Loving Christ. However, there is no spelling-out of ***how*** God and Christ will then come unto that person and abide with him or her. Except, perhaps, the mention of love on the part of the Father and the Son. Note the connection here with the individual loving Christ (knowing that the Father sent the Son). Love is definitely experienced here. This is not a whimsical emotion being spoken about; this is the *agapeo* love that is based on godly principle; that of seeking the other's benefit. 

Note also how obedience to Christ's commands are bound up with showing that that  one loves Christ. Jesus reinstated Peter after the resurrection by asking him if he (Peter) loved him, and when Peter said "You know that I love you", Christ commanded him to "Feed my sheep." Three times. (John 21:15-17) It is transparently clear - if a person claims to love Christ, they will do what Christ commands them to do. Then they will experience the *agapeo* love of the Father and the Son. And what amazing love must Peter have felt at that point of reinstatement by the One he so dearly loved!

Peter then knew that his heart-felt loathing of his sin of having denied his Lord three times had been forgiven by Christ. He experienced the loving forgiveness of Christ to him, personally. From then on, his tears were turned to singing, his hopelessness to joyful hope, and he could then launch out into his commissioned work in confident obedience. He then knew the power of the Holy Spirit in him, renewing him, transforming him, and ***that is exactly what every believer in Christ experiences when that promise of Christ works out***, as in John 14:21-23. 

God's righteousness is understood to have been supremely demonstrated at Golgotha, when the sinless Christ bore the punishment for the believer's sins. Grasping that revelation of what really was going on in the darkness of that afternoon causes the person to grasp that they have no righteousness of their own; they utterly depend on the righteousness of God to be freely pardoned and lifted up. **Putting faith in that free gift of grace causes them to know their sins are forgiven, for then their conscience is cleansed - wiped clean. There is no no more condemnation for them - and they know it because it has happened to them, personally. That is the manner of the revealing of that awesome promise**.
