I will . . . Give you as a covenant to the people.Isaiah 49:8
Jesus Christ is Himself the sum and substance of the covenant, and as one of its gifts He is the property of every believer. Believer, can you estimate what you have received in Christ? "In him the whole fullness of deity dwells bodily."1 Consider the word "God" and its infinity, and then meditate upon "perfect man" and all His beauty; for all that Christ, as God and man, ever had, or can have, is yours--out of pure free favor, given to you to be your entailed property forever.
Our blessed Jesus, as God, is omniscient, omnipresent, omnipotent. Will it not console you to know that all these great and glorious attributes are altogether yours? Has He power? That power is yours to support and strengthen you, to overcome your enemies, and to preserve you even to the end. Has He love? Well, there is not a drop of love in His heart that is not yours; you may dive into the immense ocean of His love, and you may say of it all, "It is mine." Has He justice? It may seem a stern attribute, but even that is yours, for He will by His justice see to it that all that is promised to you in the covenant of grace shall be most certainly secured to you. And all that He has as perfect man is yours. As a perfect man the Father's delight was upon Him.
He stood accepted by the Most High. O believer, God's acceptance of Christ is your acceptance; for the love that the Father set on a perfect Christ, He sets on you now. For all that Christ did is yours. That perfect righteousness which Jesus worked out, when through His stainless life He kept the law and made it honorable, is yours and is imputed to you. Christ is in the covenant.
My God, I am Thine--what a comfort divine!
What a blessing to know that the Savior is mine!
In the heavenly Lamb thrice happy I am,
And my heart it doth dance at the sound of His name.
