Jesus told a parable about a farmer who planted seed in his field, but whose enemy came and planted weeds among the wheat while the workers slept. When the crop began to grow, the weeds also grew. The farmer's workers went and reported this to him. "Should we pull out the weeds?" they asked. "No," he replied, "you'll uproot the wheat if you do. Let both grow together until the harvest. Then I will tell the harvesters to sort out the weeds." (Matthew 13:24-30). There are two important lessons here. 1. You must know God's Word so well that error, a regardless of how convincingly it's presented, can't mislead you. Paul warned the leaders of the church at Ephesus: “Even from your own number men will arise and distort the truth in order to draw away disciples after them. So be on your guard!” (Acts 20:30-31). 2. You must stay spiritually awake and alert. Notice, the seeds that were sown that night didn't produce a harvest of weeds until later. And at that point they could not be uprooted. This is dangerous! One degree off course may seem harmless enough, but if you stay on that trajectory long enough, you will end up far from where God wants you to be and realise “an enemy has done this!” So, what is the answer? “They devoted themselves to the apostles' teaching... to fellowship... the breaking of bread and... prayer' (Acts 2:42).
