Tank Less = Thankless
Mirriam Webster Dictionary says this about thankless. "Not likely to obtain thanks: unappreciated." It also means "not expressing or feeling gratitude; ungrateful."
The Bible reveals in Proverbs 23:7 an amazing truth. It says, "as a man thinks in his heart, so is he." So what you think, focus, meditate upon in your inner most being AFFECTS your world. For as you think, so are you.
Thankless is connected to think-less. You think less about all of the good things God has done for you and focus more upon things that ultimately rob and drain your love tank. Why do I focus on your "love tank?" It's because Galatians 5:9 reveals that faith works by love. The key to overcoming your challenges is your faith.
Thankful is the Key to Getting Your Tank Filled Up!
