Promises, precious promises there are for the wilderness way, and indeed the glory at the end, but properly for the way. But without promises we know God in redemption—rejoice in what He is, through what He has done, "We joy in God through our Lord Jesus Christ through whom we have received the reconciliation."
This is perfect blessedness, not what He has given, but what He is; this was the ground of the Syro-Phoenician woman—He would have had to deny Himself. We get not at promises, but at God Himself, and that by what is manifested and wrought in Christ. Promises are things given to us, but this is the Giver—this runs all through Christianity in its nature.
