I am told that it is not a good habit to allow the vehicle’s gas tank to get very low because the sediment that settles in the bottom may very well get into the engine. Whether that is technically true or not, I’ve not forgotten the advice. Admittedly, I will push the limits at times…those times when I am too hurried to stop and fill up the tank.
An empty tank is a dangerous thing ~ especially when it involves the human spirit. We are in need of regular infilling, or the sediment of the soul will surface and clog us up. Sediment looks like grumbling, complaining, consistently speaking poisonous words or projecting a nasty attitude. The technical term could be called “emissions.”
Isaiah prophesied that our gates should be Praise. “No longer will violence be heard in your land, nor ruin or destruction within your borders; but you will call your walls Salvation and your gates Praise.” [60:18]
A thankful heart stirs up the good fuel for the soul, and it avoids bitterness. In essence, it fills our tanks. It would seem that we have but two choices:  a thankful heart, or  a soul, bitter heart. Fill her up, or let her run on dregs. Emissions will tell the tale.
“I will give thanks to the Lord because of His righteousness; I will sing the praises of the name of the Lord Most High.” [Psalm 7:17] I will keep my tank filled so that emissions will be to His glory and to others’ relief!
