"Strengthen me according to Thy Word." - Psalm 119: 28
"Post guards with machine-gun vigilance at the door of your heart, because "out of it are the issues of life." (Proverbs 4:23) the most important things in life take place in the heart, such as believing unto salvation, such as loving God or our wife. The most desperately wicked things come out of the heart: '...Murderers, adulteries, fornications, thefts, false witnesses, blasphemies.' (Matthew 15:19)
Luther: 'When your heart is full of something it will run over at your mouth.'
We dare not load the naturally evil heart with more evil. Jam your heart with absolutely the best. David's determination: 'Thy Word have I hid in mine heart, that I might not sin against thee.' (Psalm 119:11)
Keep cramming it in, morning, noon, and night; memorize it, meditate on it, love it, and cherish it! You will be amazed how powerfully, repeatedly, appropriately, delightfully, the Spirit will bring to mind at exactly the right time in exactly the right place the very words you need and the people around you need."
