At times, God called people to enter into war with the goal of killing their enemies. The Bible clearly distinguishes between this type of killing and murder.
Science frequently uses natural reasoning and ordinary terminology to explain away the hand of God as He interacts with mankind. Without God, the more book learning that people get, the more ignorant they seem to become. It should come as no surprise that the Lord said that the last days would be plagued with people who could not see the truth due to their educated state (1 Timothy 6:20; Daniel 12:4; 2 Timothy 3:7). The reality is that the process of bringing a child into this world is a process that declares the handywork of God. It is God that works in the life and health of an unborn child to ensure that the child grows and matures properly. When men seek natural explanations for God’s work, they dismiss the miraculous involvement of God.
Our verbal communications involve the words that spring forth from our mouths. No doubt, the Lord considers these communications important and we should too. In today’s passage, the Lord gave some specific insights concerning His expectations of our communication. First, He wants our communication to be short and to the point – “let your communication be, Yea, yea; Nay, nay” (Matthew 5:37; see also Proverbs 10:19; Ecclesiastes 5:3, 7). Second, our word should be validated without the necessity of certifying it with vows, oaths, and swearing. In the context of the passage, the Lord Jesus forbade swearing “by heaven” (Matthew 5:34), “by the earth” (Matthew 5:35), or “by thy head” (Matthew 5:36). When we swear by these things, we put ourselves in danger of condemnation (James 5:12). Let your nay be nay and your yea be yea!
