And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve… but as for me and my house, we will serve the LORD.
The matter of man’s free will versus God’s sovereignty can be explained in this way: God’s sovereignty means that He is in control of everything, that He planned everything from the beginning. Man’s free will means that he can, anytime he wants, make most any choice he pleases (within his human limitations, of course). Man’s free will can apparently defy the purposes of God and will against the will of God. Now how do we resolve this seeming contradiction?…
Here is what I see: God Almighty is sovereign, free to do as He pleases. Among the things He is pleased to do is give me freedom to do what I please. And when I do what I please, I am fulfilling the will of God, not controverting it, for God in His sovereignty has sovereignly given me freedom to make a free choice.
Even if the choice I make is not the one God would have made for me, His sovereignty is fulfilled in my making the choice. And I can make the choice because the great sovereign God, who is completely free, said to me, “In my sovereign freedom I bestow a little bit of freedom on you. Now ‘choose you this day whom ye will serve’ (Joshua 24:15).” AOGII149-150
May I use my free will wisely, Lord, and choose wisely whom I will serve. May I be in complete submission to Your will. Amen. 
24:15 The choice here was not between the Lord and idols: Joshua assumed that the people had already decided against serving God. So he challenged them to choose between the gods which their ancestors had served in Mesopotamia and the gods of the Amorites that they had found in Canaan. Joshua’s noble decision for himself and his household has been an inspiration to succeeding generations of believers: “But as for me and my house, we will serve the Lord.”
14–15 Joshua instructs them to “serve him with all faithfulness [with integrity and truth] … serve the Lord … [and] choose … whom they will serve” (vv. 14–15). The choices are few—Israel will either serve Yahweh or the gods of the nations. Joshua links his discourse with the first portion of the historical prologue. He commands the Israelites to throw away the gods of their forefathers (Terah and Abraham) as well as the gods of the Egyptians. There is no direct textual evidence that Israel brought Mesopotamian and Egyptian gods with them. The “gods of their forefathers” may foreshadow the “gods of the Canaanites” Israel will soon encounter in the land.
24:15 choose … today whom you will serve. Joshua’s fatherly model (reminiscent of Abraham’s, Ge 18:19) was for himself and his family to serve the Lord, not false gods. He called others in Israel to this, and they committed themselves to serve the Lord also (vv. 21, 24).
24:15 choose this day whom you will serve. Joshua has urged the people to serve the Lord alone, and to put away the false gods (v. 14). Now he makes his admonition even sharper: if it is evil in their eyes to serve the Lord (i.e., if they prefer not to be loyal to the one true God, the Lord alone), then they must choose between two different categories of false gods: (1) their ancestral gods from Mesopotamia, or (2) the gods worshiped by the peoples they have dispossessed in Canaan. Joshua exercises leadership by example, committing himself and his household to serving the Lord. The people’s response was to decisively reject false gods and to serve “the Lord our God” (vv. 16–17)—which Israel did “all the days of the elders who outlived Joshua” (v. 31), but which Israel failed to do in subsequent generations, as is tragically evidenced in the book of Judges.
24:15 God must be served with exclusive loyalty (Deut. 5:7), prefiguring the exclusivity of commitment to Christ as the one way of salvation (Matt. 6:24; 10:34–39; John 14:6; Acts 4:12; 1 Cor. 10:21–22).
24:15 the gods that your ancestors served Shechem was the place at which Jacob had earlier buried the gods that his wives and concubines had brought from Haran (Gen 35:2–4). See Josh 24:14.
the Amorites Here “Amorites” refers generally to the Canaanites. Often refers to the Transjordan region (the territory of Og and Sihon; see vv. 12; Num 21; Deut 2–3).
as for me and my household Joshua and his extended family.
24:15 choose this day whom you will serve. With irony Joshua presents the alternatives that are available if the Israelites reject the Lord. The choice is between the gods Abraham left behind (vv. 2, 3) and the gods of the dispossessed Amorites (vv. 12; 2:10 note).
