God: wants us to guard the contents….
Psalm 19:14 (KJV) “Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.”
The things which proceed out of our mouths are quite likely stored in the recesses of our hearts and we pretty much haven’t been paying much attention to it’s content until it is released in the atmosphere or against someone.
But the word of God cautions us to guard our hearts and be vigilant in what we allow to placed within it.
More easily said than done or practiced.
We get easily offended and rage builds up within us; the hurt is not easily assuaged, but there is a cure.
Casting your cares upon Jesus, for He careth for us. Keep small accounts with hurts and rejection or anything which might cause the pebbles to build up within us.
