Proverbs 3:3-6, “Do not let kindness and truth leave you; Bind them around your neck, write them on the tablet of your heart, so you will find favor and good repute in the sight of God and man. Trust in the Lord with all your heart and lean not on your own understanding. In all your ways acknowledge Him and He will make your paths straight.” I titled this message “The Deadliest Sin”. What was the first thing that came into your mind? Was it murder, fornication or something else you would never do? What if I told you the deadliest sin is doubt. The Webster dictionary gives the meaning both as a verb and a noun. I will give you the meaning as a verb first. Doubt as a verb means, “to call into question the truth of”, “to lack confidence in”, “to consider unlikely”. Stop here. For those who forgot the meaning of a verb, a verb describes an action. It’s the part of a sentence often called the doing or being word. I found it interesting the dictionary gave the meaning as a noun. A noun is a word used to identify any of a class of people, places or things. I was puzzled about why the dictionary would list the word “doubt” as both a noun and a verb. So, I Googled how can a word be both a noun and a verb. It said this, “a word can be both a noun and a verb, if its form is unchanged, but its role in a sentence is different”. Why the grammar lessons, you may be thinking? The reason is this. The meaning of doubt as a noun, Webster tells us is, “the lack of confidence, an inclination not to believe or accept, a state of affairs giving rise to uncertainty”. Doubt is when our actions call into question the truth of God. When we lack confidence in Him. When we consider He is unlikely to do something. We then become the noun. We start to lack confidence. We begin to not believe or accept. We look at the state of affairs and give rise to uncertainty. Yes, the greatest sin is doubt. Hebrews 11:6 says, “And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those that seek Him.” James 1:6-8, “But let him ask in faith without any doubting; for the one who doubts is like the surf of the sea driven and tossed by the wind.”
