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

God moved through men to write the Bible. Every word of it can be used for teaching, preaching, correcting sinful behavior, and growing closer to God.

This is why we want to read it regularly. (Daily, if possible!)
