And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: {g} but as for me and my house, we will serve the LORD.

(g) This teaches us that if all the world would go from God, yet every one of us particularly is bound to cleave to him.

Wesley's Notes

24:15 Seem evil - Unjust, unreasonable or inconvenient. Choose ye - Not that he leaves them to their liberty, whether they would serve God or idols; for Joshua had no such power himself, nor could give it to any other; and both he and they were obliged by the law of Moses, to give their worship to God only, and to forbear all idolatry in themselves, and severely to punish it in others; but it is a powerful insinuation, whereby he both implies, that the worship of God is so highly reasonable, necessary and beneficial; and the service of idols so absurd, and vain, and pernicious, that if it were left free for all men to take their choice, every man in his right wits must needs chuse the service of God, before that of idols; and provokes them to bind themselves faster to God by their own choice. He will - But know this, if you should all be so base and brutish, as to prefer senseless and impotent idols, before the true and living God, it is my firm purpose, that I will, and my children, and servants (as far as I can influence them) shall be constant and faithful to the Lord. And that, whatever others do. They that resolve to serve God, must not start at being singular in it. They that are bound for heaven must be willing to swim against the stream, and must do, not as most do, but as the best do.

Matthew Henry's Concise Commentary

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.
