How do we know Christ's claims to our hearts are legitimate?

The legitimacy of Christ's claims over our hearts comes from His dual rights. First, in creation, all that belongs to Him was originally given by the Father. Secondly, through redemption, He paid the price for our sins, establishing an undeniable right over us. When the Holy Spirit moves in a person's heart, it is an affirmation of this claim, compelling us to recognize Christ's lordship and surrender our affections to Him, acknowledging that He alone deserves our worship and allegiance.
