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

Let the words of my mouth and the meditation of my heart Be acceptable in Your sight, O Lord , my rock and my Redeemer.
PSALM 19:14, NASB

Not only what we say matters, but what we think. We must let God change our minds – our way of thinking – if we want to be pleasing to Him.
