Below are some Bible verses that have special meaning to me. FAR from exhaustive. Also of course the various versions of the Great Commandment (Matthew 22:37-39, Mark 12:30-31, Luke 10:25-37).
- Micah 6:6-8
- Matthew 6:25-34
- Matthew 13:1-23 (Parable of the Sower)
- Acts 8:26-40
- I Corinthians 13 — a common wedding reading, but really about something else when read in context.
- Philippians 4:6-9
- Ephesians 4:14-16
- Ephesians 4:25
- Romans 5:18-21
- Romans 8:26
- Romans 8:38-39
Also: a good reference list of verses that support universal reconciliation, by Keith Giles.
