As King Solomon said,
Keep your heart with all diligence,
For out of it spring the issues of life.
Note that he mentioned with “all diligence”, not just when it’s convenient, or when we have time.
I am not implying to guard oneself against other people, for we are to love each other (John 13:34) , but to guard your hearts at all times.
Be very diligent with what thoughts you decide to let into your mind, and what kind of information you let in, especially unedifying conversations, gossips, social media, etc.
The heart itself is deceitful and has its scheming way of seducing us to buy information that may seem harmless.
But when we are not equipped with His knowledge, our hearts are conditioned to accept the hardest hits.
Guard your heart with His love. The heart is the source of everything we do, speak and think. With His love, only living Water overflows onto us and others.
