How do we know little sins can lead to greater sins?

The idea that little sins lead to greater ones is supported by biblical examples and human experience. Just as a small spark can ignite a devastating fire, so can a minor act of wrongdoing open the door to greater sinfulness. For instance, the story of Achan in Joshua 7 illustrates this progression; his initial decision to take a small amount of spoils led to severe consequences not only for him but also for the entire nation of Israel. Similarly, Jesus' teachings highlight how harboring even minor grievances can lead to deeper resentment and ultimately to greater sins. Therefore, recognizing the potential escalation from little sins to big transgressions is witnessing God's grace in our lives.
