S – Guard your heart above all else, for it is the source of life.

 Proverbs 4:23 CSB

O – “Heart” – lêb,  the heart; also used (fig.) very widely for the feelings, the will and even the intellect; likewise for the center of anything:

The New Strong’s Dictionary of Hebrew and Greek Words 

We should guard our heart because it is the center of all aspects of life – physical, mental, emotional and spiritual.

A – If you look at your heart like a pendulum, there will be times when the extremes are necessary and healthy.  The majority of time is spent between these extremes.  We need to grow in our ability to know when to engage less or more of our heart to a situation or person.  That is good boundaries and guards the heart.  

R – Lord, I invite your Holy Spirit to lead me today.  You know all the situations I am going to face and I need your insight to know how to release and guard my heart so that I can honor you and love others appropriately.  Continue to help to me grow in this area.
