All it takes is just reading the Bible to see that God choose people, not just Israel or the church.
Abraham in Genesis – God chose him and spoke to him. Abraham did nothing to deserve his calling. Abraham was chosen.
Nehemiah 9:7 (ESV) You are the Lord, the God who chose Abram and brought him out of Ur of the Chaldeans and gave him the name Abraham.
Israel was chosen by God not because they chose God, nor because of any good in them but because God chose them and loved them.
Deuteronomy 7:6-8 (ESV)
6 “For you are a people holy to the Lord your God. The Lord your God has chosen you to be a people for his treasured possession, out of all the peoples who are on the face of the earth.
7 It was not because you were more in number than any other people that the Lord set his love on you and chose you, for you were the fewest of all peoples,
8 but it is because the Lord loves you and is keeping the oath that he swore to your fathers, that the Lord has brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.
Jacob was chosen while Esau was rejected.
Romans 9:13 (ESV) As it is written, “Jacob I loved, but Esau I hated.”
Psalms 135:4 (ESV) For the Lord has chosen Jacob for himself, Israel as his own possession.
Isaiah 41:8-10 (ESV)
8 But you, Israel, my servant, Jacob, whom I have chosen, the offspring of Abraham, my friend;
9 you whom I took from the ends of the earth, and called from its farthest corners, saying to you, “You are my servant, I have chosen you and not cast you off”;
10 fear not, for I am with you; be not dismayed, for I am your God; I will strengthen you, I will help you, I will uphold you with my righteous right hand.
David was chosen by God. Not just the people of Israel, but God says one chosen out of the people and then specifically names David, not just the Seed of David.
Psalms 89:3-4 (ESV)
3 You have said, “I have made a covenant with my chosen one; I have sworn to David my servant:
4 ‘I will establish your offspring forever, and build your throne for all generations.’ ” Selah
Psalms 89:19-21 (ESV)
19 Of old you spoke in a vision to your godly one, and said: “I have granted help to one who is mighty; I have exalted one chosen from the people.
20 I have found David, my servant; with my holy oil I have anointed him,
21 so that my hand shall be established with him; my arm also shall strengthen him.
Psalms 78:70-71 (ESV)
70 He chose David his servant and took him from the sheepfolds;
71 from following the nursing ewes he brought him to shepherd Jacob his people, Israel his inheritance.
Solomon was chosen by God.
1 Chronicles 28:6 (ESV) He said to me, ‘It is Solomon your son who shall build my house and my courts, for I have chosen him to be my son, and I will be his father.
Zerubbabel was chosen.
Haggai 2:23 (ESV) On that day, declares the Lord of hosts, I will take you, O Zerubbabel my servant, the son of Shealtiel, declares the Lord, and make you like a signet ring, for I have chosen you, declares the Lord of hosts.”
Rufus was chosen.
Romans 16:13 (ESV) Greet Rufus, chosen in the Lord; also his mother, who has been a mother to me as well.
Paul was chosen.
Acts 22:14 (ESV) And he said, ‘The God of our fathers appointed you to know his will, to see the Righteous One and to hear a voice from his mouth;
Acts 22:14 (KJV) And he said, The God of our fathers hath chosen thee, that thou shouldest know his will, and see that Just One, and shouldest hear the voice of his mouth.
Galatians 1:15-16 (ESV)
15 But when he who had set me apart before I was born, and who called me by his grace,
16 was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not immediately consult with anyone;
So why is it such a stretch for some to believe that God calls, elects, or chooses people? Doesn’t seem to be able to be any plainer than this:
John 15:16-19 (ESV)
16 You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide, so that whatever you ask the Father in my name, he may give it to you.
17 These things I command you, so that you will love one another.
18 “If the world hates you, know that it has hated me before it hated you.
19 If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you.
Whom does this refer to but to you?
