Small decisions rarely seem important in the moment. A harsh word, a dishonest shortcut, or a selfish thought can feel insignificant.
But sin often begins the same way a seed is planted in the ground.
At first, nothing seems to happen. A thought appears. A temptation passes through the mind. If it is rejected, it dies there.
But if it is accepted and planted, it begins to grow into something far worse than it first appeared.
Over time that small seed can produce something far worse than it first appeared. Scripture repeatedly warns that sin does not remain small. What begins in the heart eventually grows into actions and consequences.
In this sense, there are two kinds of seeds being sown in the world.
God plants the seed of the Gospel, bringing life and salvation. But Satan also plants seeds—temptations and sinful thoughts—hoping they will be accepted and cultivated.
Every day seeds are being scattered. The question is whether they are rejected, or planted and allowed to grow.
James 1:14–15
Each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death.
Galatians 6:7
Whatever a man sows, that he will also reap.
Matthew 13:3–9
He told many stories in the form of parables, such as this one: “Listen! A farmer went out to plant some seeds. As he scattered them across his field, some seeds fell on a footpath, and the birds came and ate them. Other seeds fell on shallow soil with underlying rock. The seeds sprouted quickly because the soil was shallow. But the plants soon wilted under the hot sun, and since they didn’t have deep roots, they died. Other seeds fell among thorns that grew up and choked out the tender plants. Still other seeds fell on fertile soil, and they produced a crop that was thirty, sixty, and even a hundred times as much as had been planted! Anyone with ears to hear should listen and understand.
Summary
The most effective place to fight sin is at the thought level, before the seed ever takes root.
