I shall have peace, thaugh I walk in the stubbornness of mine heart - Deuteronomy 29:19
So man's foolish heart reasons. He hears the curse pronounced against sin; he knows that the man who turns from God is threatened with gall and wormwood, and yet he persists in his evil ways, secretly blessing himself, and laying the flattering unction to his heart that he at least will come off scot free. Such an one is an abomination to the Lord, and shall not escape: "The Lord will not pardon him, but His anger shall smoke against him." It is still true of the wicked, "that every imagination of the thoughts of his heart is only evil continually."
The only way to peace is by abjuring the stubbornness which sets up its own will and way against God's. Is not this the secret of the unrest of your soul - that you have never perfectly yielded to God? You know that if others did as you do, and cherished the dispositions that you permit, you would instantly condemn them, and assure them of the incompatibility of soul-rest and such things as these; but you bless yourself, and say, "I shall have peace, though I walk in the stubbornness of my heart."
Ask God to take the stubbornness out of you, to rid you of your hard heart, to bring you into loving, gentle subordination to Himself; to fulfill His promise in your experience, "I will take the stony heart out of their flesh, and will give them a heart of flesh." Return and submit. Take His yoke and learn of Him. Bow down at His feet. Let every step of your daily walk be taken in the track of His holy will. So shall you find rest unto your soul; and the peace of God, which passeth all understanding, shall guard your hearts and your thoughts in Christ Jesus" (Phi 4:7, R. V.).
