Some verses from “that all shall be saved,” by David Bentley Hart, in support of universal salvation:

Romans 5:8-19 | So, then, just as through one transgression came condemnation for all human beings, so also through one act of righteousness came a rectification of life for all human beings; for, just as by the heedlessness of the one man the many were rendered sinners, so also by the obedience of the one the many will be rendered righteous.

Titus 2:11 | For the grace of God has appeared, giving salvation to all human beings …

Matthew 18:14 | So it is not a desire that occurs to your Father in the heavens that one of these little ones should perish.

1 John 2:2 | And he is atonement for our sins, and not only for ours, but for the whole cosmos.

1 Timothy 4:10 | we have hoped in a living God who is the savior of all human beings, especially those who have faith.
