The Bible often defines words through their associations. For instance, the words salute, saluteth, and salutation involve a greeting.
When speaking of anger, the scripture uses descriptive terms that could equally be applied to the truths concerning fire. In doing so, the Bible makes a connection that can help believers gain a better understanding of the benefits or dangers of anger. According to scripture, anger can be kindled, a term used to describe the starting of a fire (Exodus 4:14; Numbers 11:1; Deuteronomy 32:22; Jeremiah 15:14), either a little (Psalm 2:12) or greatly (Numbers 11:10; 1 Samuel 11:6). The Bible also describes anger as waxing hot (Exodus 32:19), another connection to fire. These similarities are by divine design. As is true concerning fire, anger can be useful and productive, but it can also be destructive and harmful, especially when it gets out of control.
Fear introduced is faith attacked. As such, we should not be partakers of the world’s fears. Instead, we should “sanctify the LORD of hosts himself; and let him be” our fear (Isaiah 8:13). Throughout scripture, the Lord admonished His people not to fear the world. Why? The answer is twofold: (1) the Lord was with them (Genesis 26:24) and (2) fear of the world yields bondage (Proverbs 29:25). This worldly bondage never originates with the Lord (Romans 8:15) for He has given Christians a sound mind (2 Timothy 1:7). We need not fear those who can destroy the body (Matthew 10:28); rather, we ought to say the Lord is our helper, and we will not fear what men will do unto us (Hebrews 13:6).
Courage originates within the heart of the individual. Two chief witnesses testify to this truth: (1) The English word courage comes from a word plainly connected to the heart, and (2) MultipleBible passages associate courage with the heart (Numbers 32:7, 9; Deuteronomy 1:28; Psalm 27:4; Psalm 31:24). The scripture declares in our passage that the hearts of the people melted as they lost courage (i.e., they lost strength). Other Bible passages associate courage with the strengthening of the heart (Psalm 27:14; Psalm 31:24). These truths illustrate that courage reflects strength of heart and that courage is based upon faith, hope, and trust in God.
