How do we know the need for laborers is true?

In Luke 10:2, Jesus states, 'The harvest truly is great, but the laborers are few.' This declaration reflects both the abundant opportunity for salvation and the urgent need for faithful workers to proclaim the gospel. This principle is echoed in Romans 10:14-15, where the necessity of preaching for people to believe is laid out clearly. The need for gospel laborers today remains critical as many remain unengaged with the truth, underscoring the importance of prayer for more to be sent out.
