Christ said, "You did not choose me but I choose [SIC; chose]
you." (John 15:16) The whole Old Testament is dedicated to "a chosen people", a "holy nation".
Yet He did not say that to just anyone; that was said to the twelve disciples/apostles celebrating Passover with Him (see chapter thirteen). He did choose them, as shown in the Gospels. As for the chosen people, Moses (speaking for the LORD) told the Israelites to choose.
I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: That thou mayest love the Lord thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the Lord sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.

I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.

Yes, Moses told the people to choose life in Deut 30. In Deut 31 God told Moses the people won't do it:
Deu 31:16 And the LORD said to Moses, "Behold, you are about to lie down with your fathers. Then this people will rise and whore after the foreign gods among them in the land that they are entering, and they will forsake me and break my covenant that I have made with them.
And God was right. That is our wicked and perverse nature.
