Hopefully making theology simpler to understand! (2 Corinthians 1:12)

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.
2 Timothy 3:16‭-‬17, ESV

We need not unhitch from the Old Testament nor attempt to reinterpret any of the Bible for our modern context.
All of Scripture points us to the Son of God, Jesus, amd shows us the best way to imitate Him in righteousness.
