He has commanded his covenant forever.Psalms 111:9
The Lord's people delight in the covenant itself. It is an unfailing source of comfort to them as often as the Holy Spirit leads them into the banqueting house and waves the banner of love. They delight to contemplate the antiquity of that covenant, remembering that before the daystar knew its place or planets ran their course, the interests of the saints were made secure in Christ Jesus. It is peculiarly pleasing to them to remember the certainty of the covenant while meditating upon God's "steadfast, sure love David."1 They delight to celebrate it as signed, sealed, and delivered! Their hearts often overflow with joy to think of its immutability, as a covenant that neither time nor eternity, life nor death will ever be able to break-a covenant as old as eternity and as everlasting as the Rock of Ages.
They rejoice also to dine upon the fullness of this covenant, for in it they see all things provided for them. God is their portion, Christ their companion, the Spirit their Comforter, earth their lodge, and heaven their home. They see in it an inheritance that is reserved for every soul possessing an interest in its ancient and eternal gift. Their eyes sparkled when they saw it as a treasure-trove in the Bible; but how their souls were gladdened when they saw in the last will and testament of their Christ that it was bequeathed to them!
More especially it is the pleasure of God's people to contemplate the graciousness of this covenant. They see that the law was made void because it was a covenant of works and depended upon merit, but they perceive this to be enduring because grace is the basis, grace the condition, grace the bulwark, grace the foundation, grace the capstone. The covenant is a treasury of wealth, a granary of food, a fountain of life, a storehouse of salvation, a charter of peace, and a haven of joy.
