There’s a sense in which home ownership has two corresponding realities. There’s the objective reality. When the funds are confirmed and the mortgage is signed the house is owned. It’s a done deal. But there’s also the subjective reality. This is the process by which the owner grows in their experience of their ownership by moving-in, unpacking and renovating, and sharing their home with others. In these ways, the objective reality becomes increasingly experienced and enjoyed.
Similarly, when an individual places their faith in Jesus Christ the payment has been made, the deed has been signed, and the Lord is now their owner. It’s objectively a done deal. But there’s also a subjectivity—a process by which believers can grow in the experience, enjoyment, and certainty their salvation by the work of the Holy Spirit as he moves-in to his new home (indwells), unpacks in his new home (seals), and shares his new home (testifies).
