“Others, like seed sown on good soil, hear the word, accept it, and produce a crop—thirty, sixty or even a hundred times what was sown.”
In the parable of the soils Jesus tells of different types of people who hear the gospel. Only some people hear the word of God and accept it and will bear fruit as a result of this.
As a seed reaches maturity it produces a great harvest in light of what was invested. One seed does not return one seed; it returns dozens of tomatoes or years of apple harvesting.
Bearing fruit takes time and some of us will take longer to reach maturity than others. Some Christians go through years of backsliding after their initial profession of faith before they get their life together. Others see a rapid change in their life.
Christians are going to have different levels of production. God has gifted each person differently and we shouldn’t expect each Christian to do the same things. Some people are going to be the equivalent of the crop that is thirty times what was sown while others are going to be like the crop that is sixty or a hundred times what was sown.
We are called to bear fruit. The amount that is produced depends on our maturity and how we are gifted. We have control over our maturity only. Produce fruit and strive for maturity. Don’t worry about the results. God is looking for fruit, not the numbers.
