Verse 7. Wherefore. In view of the fact that the Author of the Christian dispensation has a rank far superior to that of Moses. Because Christ has claims on us far greater than those which Moses had, let us hearken to his voice, and dread his displeasure.

As the Holy Ghost saith. In Ps 95:7-11. This is full proof that, in the estimation of the author of this epistle, the writer of this Psalm was inspired. The Holy Ghost speaks through the word which he has revealed. The apostle quotes this passage, and applies it to those whom he addressed, because the admonition was as pertinent and important under the Christian dispensation as it was under the Jewish. The danger of hardening the heart by neglecting to hear his voice was as great, and the consequences would be as fearful and alarming. -- We should regard the solemn warnings in the Old Testament against sin, and against the danger of apostasy, as addressed by the Holy Ghost to us. They are as applicable to us as they were to those to whom they were at first addressed; and we need all the influence of such appeals, to keep us from apostasy, as much as they did.

Today. Now; at present. At the very time when the command is addressed to you. It is not to be put off till tomorrow. All God's commands relate to the present -- to this day -- to the passing moment. He gives us no commands about the future, he does not require us to repent; and to turn to him to-morrow, or ten years hence. The reasons are obvious.

(1.) Duty pertains to the present. It is our duty to turn from sin, and to love him now.

(2.) We know not that we shall live to another day. A command, therefore, could not extend to that time, unless it were accompanied with a revelation that we should live till then -- and such a revelation God does not choose to give. Every one, therefore, should feel that whatever commands God addresses to him are addressed to him now. Whatever guilt he incurs by neglecting those commands is incurred now. For the present neglect and disobedience each one is to answer -- and each one must give account to God for what he does TODAY.

If ye will hear. In case you are willing to hearken to God, listen now, and do not defer it to a future period. -- There is much in a willingness to hear the voice of God. A willingness to learn is usually the precursor of great attainments in knowledge. A willingness to reform is usually the precursor of reformation. Get a man willing to break off his habits of profaneness or intemperance, and usually all the rest is easy. The great difficulty in the mind of a sinner is in his will. He is unwilling to hear the voice of God; unwilling that he should reign over him; unwilling now to attend to religion. While this unwillingness lasts he will make no efforts, and he sees, or creates, a thousand difficulties in the way of his becoming a Christian. But when that unwillingness is overcome, and he is disposed to engage in the work of religion, difficulties vanish, and the work of salvation becomes easy.

His voice. The voice of God speaking to us

(1.) in his written word;

(2.) in the preached gospel;

(3.) in our own consciences;

(4.) in the events of his Providence;

(5.) in the admonitions of our relatives and friends. Whatever conveys to us the truth of God, or is adapted to impress that on us, may be regarded as his voice speaking to us. He thus speaks to us every day in some of these ways; and every day, therefore, he may entreat us not to harden our hearts.
