How do we know that diligent prayer is essential for ministry?

Diligent prayer serves as a means through which spiritual wisdom and guidance are frequently received. Proverbs 16:23 states, 'The heart of the wise teaches his mouth, and adds learning to his lips,' highlighting the connection between a life of prayer and the wisdom necessary for effective preaching. Diligent prayer stems from a genuine sense of God's love, the worth of souls, and the fleeting nature of time. When ministerial efforts are undergirded by fervent prayer, they become dynamic and fueled by the Holy Spirit, leading to fruitful ministry, rather than self-reliant endeavors that produce little spiritual benefit.
