I love Proverbs 4:23:
Above all else, guard your heart, for it is the wellspring of life.

I always use this verse to teach about purity. Specifically sexual purity.
Ok, sure, the verse works for that.

But it applies in so many other ways.

Don’t just guard your heart against lust.

Guard it against discouragement. Guard it against pride. Guard it against doubt. Insecurity. Jealousy. Distraction.

Be selective about who gets backstage access in your life.

You can’t let just anyone into your world to speak into your soul.
Be careful who you share your dreams with.
Their negativity can contaminate the possibility before it ever has a chance to become a reality.

Be careful who you take advice from.
Their immaturity or ignorance might confuse the issue and create needless chaos.

Everything flows from the heart.
Put it on lock down… like Fort Knox.
You’ve got valuable stuff in there.
