Have you ever just listened to someone talk. It is said that what comes from the mouth originates from the heart.
The bible is very clear. James writes in James 1:26
James 1:26 Those who consider themselves religious and yet do not keep a tight rein on their tongues deceive themselves, and their religion is worthless.
I can’t get over how many proclaimed Christians can unleash a flurry of words that would blush most sailors (and I was in the Navy) yet justify their speech as ‘its who I am’. For those new to Christ there will be a conviction that, over time, will cause a miraculous change in the words they use.
However, for those who have been seasoned in Christ over several years, I encourage you to pray and study Pslam 141:3
Set a guard, O LORD, over my mouth; Keep watch over the door of my lips.
May the Lord fill your heart with Joy and Thanksgiving so that what you say reflects your heart as a testament to Him.
