“I am the Lord thy God.”
It is a wonderful thing to say “I have given myself to God.” It is even more wonderful to say that God has given Himself to me! He is my God! He says “I am the Lord thy God.” Let’s read from a great Puritan as he describes this wonderful Gift.
Herein is the propriety, and indeed here is the mercy, that God speaks thus to every faithful soul, “I am thy God.” By this appropriation God gives us a right in him, yea, a possession of him. 1. A right in him: as the woman may say of him to whom she is married, this man is my husband, so may every faithful soul say of the Lord, he is my God. 2. A possession of him: God doth not only show himself unto us, but he doth communicate himself unto us in his holiness, mercy, truth, grace, and goodness; hence it is said, “We have fellowship with the Father, and with his Son Jesus Christ.” Herein God gives himself to be wholly ours, consider God essentially or personally. Consider Jehovah Elohim, all is ours. God, in his essence and glorious attributes, communicates himself to us for good; and God, personally considered, as Father, Son, and Holy Ghost, they all enter into covenant with us.
[1.] The Father enters into covenant with us. He promiseth to be a Father to us: hence saith the Lord, “Israel is my Son, my first-born.”
[2.] The Son is in covenant with us, and speaks to us in this language; “Thou art mine; I have redeemed thee, I have called thee by thy name, and therefore thou art mine.” This is Christ’s covenant with us; he brings us back to his Father, from whose presence we were banished, and sets us before his face for ever. He promiseth to restore us to the adoption of sons; and not only to the title, but to the inheritance of sons, that we might be where he is.
[3.] The Holy Ghost makes a covenant with us. “By one offering he hath perfected for ever them that are sanctified; whereof the Holy Ghost also is a witness.” “This is the covenant that I will make with them; I will put my law into their hearts, and in their minds will I write them.” I know the Father is implied in this, yet here is the proper work of the Holy Ghost. What the Father hath purposed, and the Son hath purchased for us, that the Holy Ghost effects in us. He applies the blood of Christ for the remission of sins; he writes the law in our hearts; he comforts us in our sadness; he supports us in our faintings and guides us in our wanderings. Now in that he effects these things for us, and in our behalf, he is said to make a covenant with us. Thus Elohim, God personally considered, Father, Son, and Holy Ghost, are in covenant with us. Isaac Ambrose 1653 AD.
