Bible passages indicating that humans can choose salvation (or not)

I am aware that there are those, and they may be right, who believe that we can't really choose whether ot not to accept Christ's resurrected sacrifice for our sins, and His lordship. However, there are some Bible passages that indicated that we do have a choice in the matter. I will give them below, without presenting the Biblical evidence to the contrary -- and there is such evidence. See the Wikipedia article on predestination.

All quotations are from the World English Bible, which is public domain.

Some of these passages don't seem to say anything directly about free choice, but I have also included passages that indicate that salvation is for all people.

John 3:16 For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.

Acts 2:21 It will be that whoever will call on the name of the Lord will be saved.

Romans 5:17 For if by the trespass of the one, death reigned through the one; so much more will those who receive the abundance of grace and of the gift of righteousness reign in life through the one, Jesus Christ. 18 So then as through one trespass, all men were condemned; even so through one act of righteousness, all men were justified to life.

Romans 10:13 For, “Whoever will call on the name of the Lord will be saved.” (This quotes Leviticus 18:5, as does Acts 2:21.)

1 Timothy 2:5 For there is one God, and one mediator between God and men, the man Christ Jesus, 6 who gave himself as a ransom for all; the testimony in its own times;

1 Timothy 4:10 For to this end we both labor and suffer reproach, because we have set our trust in the living God, who is the Savior of all men, especially of those who believe.

1 John 2:2 And he is the atoning sacrifice for our sins, and not for ours only, but also for the whole world.

Revelation 3:20 Behold, I stand at the door and knock. If anyone hears my voice and opens the door, then I will come in to him, and will dine with him, and he with me.

Revelation 22:17 The Spirit and the bride say, “Come!” He who hears, let him say, “Come!” He who is thirsty, let him come. He who desires, let him take the water of life freely.

Thanks for reading!
