“And I will be their God, and they shall be My people.” (Jer. 24:7)
Do not pass these words lightly. They express the very highest experience of the Covenant relationship. It is only when His people learn to love and obey His law, when their heart and life are together wholly devoted to Him and His will, that He can be to them the altogether inconceivable blessing which these words express, “I will be your God.” All I am and have as God shall be yours. All you can need or wish for in a God, I will be to you. In the fullest meaning of the word, I, the Omnipresent, will be ever present with you, in all My grace and love. I, the Almighty One, will each moment work all in you by My mighty power. I, the Thrice Holy One, will reveal My sanctifying life within You. I will be your God. And ye shall be My people, saved and blessed, ruled and guided and provided for by Me, known and seen to be indeed the people of the Holy One, the God of glory. Only let us give our hearts time to meditate and wait for the Holy Spirit to work in us all that these words mean.
But why, if all this is meant to be literally and exactly true of God’s people, why do we see so little of this life, experience so little in ourselves? There is but one answer: Because of your unbelief! We have spoken of the relation of God and man in creation as what the New Covenant is meant to make possible and real. But the law cannot be repealed that God will not compel. He can only fulfil His purpose as the heart is willing and accepts His offer. In the New Covenant all is of faith. Let us turn away from what human wisdom and human experience may say, and ask God Himself to teach us what His Covenant means. If we persevere in this prayer in a humble and teachable spirit, we can count most certainly on its promise: “They shall no more every man teach his neighbor: Know the Lord, for they shall all know Me.” The teaching of God Himself, by the Holy Spirit, to make us understand what He says to us in His Word, is our Covenant right. Let us count upon it. It is only by a God-given faith that we can appropriate these God-given promises. And it is only by a God-given teaching and inward illumination that we can see their meaning, so as to believe them. When God teaches us the meaning of His promises in a heart yielded to His Holy Spirit, then alone we can believe and receive them in a power which makes them a reality in our life.
Do let us turn our hearts away from all past experience of failure, as caused by nothing but unbelief; do let us admit fully and heartily, what failure has taught us, the absolute impossibility of even a regenerate man walking in God’s law in his own strength, and then turn our hearts quietly and trustfully to our own Covenant God. Let us hear what He says He will do for us, and believe Him; let us rest on His unchangeable faithfulness and the surety of the Covenant, on His Almighty power and the Holy Spirit working in us; and let us give up ourselves to Him as our God. He will prove that what He has done for us in Christ is not one whit more wonderful than what He will do in us every day by the Spirit of Christ. (Andrew Murray)
