I. THEY ARE THE GREAT SOURCES OF UNREALITY IN RELIGION. In sending Jeremiah to God they did not mean what they said. There was no honest willingness to do as the prophet might reveal. The only hope for them in their forlorn condition is thus tampered with and destroyed. It is possible that at first they may have meant well, but as they proceeded with their inquiry through the prophet they must have known that they had only one intention, which they had not laid aside or even held in abeyance. Yet such is the subtlety of the hypocritical heart that it continues in its hypocrisy until it deceives itself. "They inquire not to learn what is right, but only to receive encouragement to do what they wish."

II. THOSE WHO INDULGE THEM ARE THEIR OWN WORST ENEMIES.

1. They deceive and injure themselves. "Ye dissembled in your hearts" (ver. 20); literally, deceived yourselves; "used deceit against your souls" (margin). Thinking they were taking counsel of God, they were really obeying their fears and lusts. Can a greater wrong be done to one's self than this - to think one's self religious and obedient to the heavenly will when one is only selfish and sinful? Safety and happiness lay in following simply the Divine guidance; but this they could not do, for they knew not God's message when it came. "Thinking themselves wise, they became fools." Their spiritual nature is henceforth unreliable, and their greatest perils will be encountered in their most religious hours, and when they think themselves most in agreement with God's will.

2. The curse of God is denounced against them. What they choose will be their destruction. The very things they sought to avoid by going to Egypt are met there. And there is no mitigation; the position is one wholly wrong, and consequently the wrath of God is unceasing until they cease to occupy it. To remain in Egypt, with its idolatries and abominations, was virtually to annul the covenant. Soon every trace of true religion would disappear, and they would become like their neighbours, and be absorbed into the nations in whom God had no pleasure. He cannot tolerate falsehood, pretension, the form of godliness without the reality. And this severity is true mercy. Many a one "plucked as a brand from the burning" has had reason to thank his Saviour that "the way of transgressors is hard." "Let a man examine himself." "Be not deceived: God is not mocked." - M.

II. WHEN THEY WHO DESIRE THE PRAYERS OF OTHERS MAY BE SAID TO DISSEMBLE IN THEIR HEARTS. They do so when they desire them without sincerity; when they will not pray for themselves; when they will not use proper means to obtain the blessings they desire; and especially when they will not do what God by His Word and ministers requireth.

III. THE HYPOCRISY AND EVIL OF THIS CONDUCT. It is an affront to the all-seeing and holy God; it is likewise deceiving their friends; and prayers offered for such persons are not likely to be of much avail. Application —

1. We may hence learn, with what dispositions of mind we should desire the prayers of others. Whenever we ask the intercessions of others, let it be in sincerity; with a firm persuasion of the power of prayer; that it is not in vain to seek God; and that it is our duty to engage the assistance of our friends, by their application to the throne of grace. Be solicitous that you concur with them by praying yourselves without ceasing in the best manner you are able; and with your chief dependence for acceptance, not on your own prayers, nor those of your friends, but the mediation of Jesus Christ.

2. That we should be ready to pray one for another. Whenever we think of an absent relation or friend, or hear of him, or receive a letter from him, let us lift up our hearts to God for him in a short petition, as his circumstances may require. But we should be particularly mindful of those who desire our prayers.

3. It is peculiarly wicked to dissemble in our hearts, when we profess dependence on the intercession of Christ.

(Job Orion, D. D.)
