“Keep thy heart with all diligence; for out of it are the issues of life.” Proverbs 4:23
So often I’ve read it as a stand-alone thought but the context is so key…
put away a froward mouth,
put away perverse lips (FAR away)
Eyes, look right on - straight before thee,
Ponder path of my feet, ways be established, remove my foot from evil.
It was a reminder that complaining, murmurings and disputings (that froward mouth) can cause me to lose my heart in that area. It is a sin against God.
I am glad that God reminds, again and again and doesn’t give up on me! aren’t you?
