Even Gentiles, who do not have God’s written law, show that they know his law when they instinctively obey it, even without having heard it. They demonstrate that God’s law is written in their hearts, for their own conscience and thoughts either accuse them or tell them they are doing right. [Romans 2:14-15 (NLT)]
Looking back, I realize we’d heard a chirp once or twice earlier that day but had ignored it. Busy running errands, we’d given the odd sound no thought. At 12:22 AM, however, the source became obvious and could no longer be ignored. The bedroom smoke alarm was chirping loudly every minute or so. I looked at my husband with envy—without his hearing aids, he was oblivious to the annoying noise above our heads. Since there was no way I was going to return to slumber, I woke him and we replaced the battery. Two nights later, when the same thing happened with the brand new battery, we simply took it out and went back to bed. I’m embarrassed to admit we had no battery in that alarm for the next several months. Since 60% of home fire deaths occur in properties without a working smoke alarm, we were foolish to ignore the problem.
Rather than replacing the battery, we actually needed to replace our 15-year old smoke alarms. The U.S. Fire Administration (part of FEMA), suggests replacing smoke alarms every ten years. After a decade, alarm sensors are compromised by dust, insects, contaminants and circuitry corrosion and their failure rate is 30%.
The smoke alarm got me thinking about another alarm we have—conscience. Made in the image of God, we all have an innate understanding of right and wrong, good and evil. Like a smoke alarm, however, its sensors can fail to work properly. Rather than dust or spider webs, things like pride, selfishness, prejudice, materialism, envy, and jealousy can corrode its circuits. Fallible, it can be convinced to condone, excuse, or justify the indefensible, inexcusable, and sinful. By themselves, consciences can be as unreliable as thirty year old smoke alarms (nearly all of which fail).
Fortunately, as Christians, we have something in addition to a conscience—the voice of the Holy Spirit. It is His voice that points us to God’s ways. His presence renews and reshapes our conscience into a much bigger and better alarm—one based on God’s word rather than convenience or objectives. While we can manipulate our conscience into seeing things our way, we can’t sway the Holy Spirit; God’s standards don’t change with the situation or our desires. Moreover, the Spirit’s voice doesn’t stop at determining right from wrong; it convicts us of the need for repentance and change. It’s like the new smoke alarms we now have that interconnect, inform us of the type and location of the danger, and tell us to evacuate. Fortunately, instead of a seven year warranty, the Holy Spirit can last a lifetime!
Our new improved Holy Spirit-powered conscience won’t do us much good if we don’t recognize and heed it. Unless we read God’s word, it’s easy to mistake which voice we’re hearing (ours or the Spirit’s). While gentle and loving, the Spirit’s voice can be brutally honest and, like a smoke alarm, it demands action. When the Psalmist asked God to point out anything He found offensive, he had to expect a truthful answer and one that he might not like. Although we can’t remove the Spirit’s batteries, we can ignore His words of conviction. Like those people without functioning smoke alarms, however, we do so at our own risk.
Let us therefore not deceive ourselves. In walking according to the spirit we shall hear the direction of conscience. Do not try to escape any inward reproach; rather, be attentive to its voice. [Watchman Nee]

Wow! Now there’s a troubling verse. God creates evil? Since evil is anything that contradicts God’s holy nature, it’s hard to understand how that could happen. Even other translations like the NLT’s, “I send good times and bad times,” the ESV’s, “I make well-being and create calamity,” and the NIV’s, “I bring prosperity and create disaster,” don’t make this verse sound much better. How do we reconcile a God who is good, a God who is love, with a God who says he creates evil?
Skeptics often point to contradictions in the Bible when questioning its reliability. For example, Matthew, Mark and Luke tell of Jesus healing a demon-possessed man and casting the demons into swine but there are inconsistencies between their accounts. Mark and Luke say this occurred in the region of the Gerasenes but Matthew calls it the Gadarenes. In this region, however, there were at least three towns with similar names: Gergasa, Gerasa and Gadara. Adding to the confusion, once healed, the demoniac testified throughout what was called the Decapolis or Ten Towns and both Gadara and Gerasa were in this district. The area of the Gerasenes probably included that of the Gadarenes in the way someone living in Hammond, Indiana, also lives in Lake County, on the South Shore, in northeast Indiana, and within the Chicago metropolitan area. The same place can be described many ways.
When discussing whales, the 3rd grade science teacher insisted that because of the whale’s small throat it was physically impossible for one to swallow a human. Disagreeing, the little girl told her that Jonah had been swallowed by a whale. When the teacher insisted it was just a silly story, the girl said that when she got to heaven she would ask Jonah. ”Well,” replied the teacher scornfully, “What if Jonah isn’t there? What if he went to hell?” The little girl politely answered, “Then I guess you can ask him!”
After asking us how we protect our personal safety, the cyber-security specialist asked how we protect ourselves from cyber attacks. One woman proudly told how Microsoft had recently saved her from a hacking attempt. After a message popped up telling her to call them, she gave them remote access to her computer. The necessary patch and technical advice only cost $700 and now her computer was secure. Until the speaker told her, she didn’t know the hack was the $700 she’d spent, access to her credit card, and possible malware now active on her computer. While she never would have allowed a complete stranger into her home, she unwittingly opened the door to a criminal and welcomed him into her life.
