24:15-28 It is essential that the service of God's people be performed with a willing mind. For LOVE is the only genuine principle whence all acceptable service of God can spring. The Father seeks only such to worship him, as worship him in spirit and in truth. The carnal mind of man is enmity against God, therefore, is not capable of such spiritual worship. Hence the necessity of being born again. But numbers rest in mere forms, as tasks imposed upon them. Joshua puts them to their choice; but not as if it were indifferent whether they served God or not. Choose you whom ye will serve, now the matter is laid plainly before you. He resolves to do this, whatever others did. Those that are bound for heaven, must be willing to swim against the stream. They must not do as the most do, but as the best do. And no one can behave himself as he ought in any station, who does not deeply consider his religious duties in family relations. The Israelites agree with Joshua, being influenced by the example of a man who had been so great a blessing to them; We also will serve the Lord. See how much good great men do, by their influence, if zealous in religion. Joshua brings them to express full purpose of heart to cleave to the Lord. They must come off from all confidence in their own sufficiency, else their purposes would be in vain. The service of God being made their deliberate choice, Joshua binds them to it by a solemn covenant. He set up a monument of it. In this affecting manner Joshua took his last leave of them; if they perished, their blood would be upon their own heads. Though the house of God, the Lord's table, and even the walls and trees before which we have uttered our solemn purposes of serving him, would bear witness against us if we deny him, yet we may trust in him, that he will put his fear into our hearts, that we shall not depart from him. God alone can give grace, yet he blesses our endeavours to engage men to his service.Choose - Service of God in sincerity and truth can only result from a free and willing allegiance of the heart. This accordingly is what Joshua invites, as Moses had done before him (Deuteronomy 30:15 ff). 14-28. Now therefore fear the Lord, and serve him in sincerity and in truth—After having enumerated so many grounds for national gratitude, Joshua calls on them to declare, in a public and solemn manner, whether they will be faithful and obedient to the God of Israel. He avowed this to be his own unalterable resolution, and urged them, if they were sincere in making a similar avowal, "to put away the strange gods that were among them"—a requirement which seems to imply that some were suspected of a strong hankering for, or concealed practice of, the idolatry, whether in the form of Zabaism, the fire-worship of their Chaldean ancestors, or the grosser superstitions of the Canaanites. Ye are witnesses against yourselves; this solemn profession will be a swift witness against you, if hereafter you apostatize from God.

And Joshua said unto the people,.... In reply to their answer and resolution:

ye are witnesses against yourselves, that ye have chosen you the Lord God to serve him; that is, should they, after this choice of him, which they had so publicly declared, desert his service, and go into idolatry, their testimony would rise up against them, and they would, be self-condemned:

and they said, we are witnesses; should we ever apostatize from the Lord and his worship, we are content to have this our witness produced against us.

And Joshua said unto the people, Ye are witnesses {i} against yourselves that ye have chosen you the LORD, to serve him. And they said, We are witnesses.

(i) If you do the contrary, your own mouths will condemn you.
