“I have stored up your word in my heart, that I might not sin against you.”
‭‭Psalm‬ ‭119:11‬ ‭ESV‬‬

There’s not really more to say about this. If His word fills our hearts then there’s not much room left for sin to take hold. While reading His word daily is a good first step, I know I need to commit more of His word to my heart by memorization in not just the words but the meaning and love behind them.
