When I was pregnant with Glory, my second child, I went through a time when I vomited quite often. The longer the episode lasted the harder it seemed to get it to cease. After awhile, I found that if I could stop vomiting long enough to take a sip of a fizzy sweet drink it would actually help calm the gag reflex and help bring me out of the repetitive cycle.
I think the same is true with the words we speak. Sometimes we get into cycles where the things that proceed from our heart and lips are like vomit. They are negative, death and destruction. Truly the Word of God is the sweet drink we can put to our lips to stop the cycle. When we meditate on the Word of God, it brings life! When we are filled with life, that is what will flow from our lips!
My child, be attentive to my words;
incline your ear to my sayings.
Do not let them escape from your sight;
keep them within your heart.
For they are life to those who find them,
and healing to all their flesh.
