“We enjoy Christ only as we embrace Christ clad in His own promises.
Thus it comes to pass that he indeed dwells in our hearts [cf. Eph. 3:17], and yet: “We are absent from him. For we walk by faith, not by sight” [2 Cor. 5:5–7].
Now these two things agree rather well with each other: we possess in Christ all that pertains to the perfection of heavenly life, and yet faith is the vision of good things not seen [cf. Heb. 11:1].
Only, we must note a difference in the nature or quality of the promises: the gospel points out with the finger what the law foreshadowed under types.”
