A.W. Pink expounds on 'The Parable of the Mustard-Seed,' emphasizing that the parable illustrates the corrupting influence of worldly systems on the true nature of the Kingdom of Heaven. He argues against the popular interpretation that sees the mustard seed as a symbol of the Gospel's success, instead suggesting that the growth into a tree represents a deviation from the original intent of Christ's teachings. Pink highlights that the 'birds of the air' symbolize Satan and his agents, who find refuge in this corrupted system, indicating a departure from the true essence of Christianity. The sermon warns against the dangers of worldly prominence and the infiltration of falsehood within the Church, ultimately portraying a somber view of the historical development of Christendom. Pink's analysis serves as a call to discernment regarding the true nature of the Kingdom of Heaven amidst the challenges of worldly influence.

A.W. Pink explores 'The Parable of the Leaven,' emphasizing that the leaven symbolizes corrupting evil rather than the Gospel. He argues that the common interpretation, which views leaven as good and the meal as humanity, contradicts Christ's teachings in the preceding parables and the broader context of Scripture. Pink asserts that the 'woman' represents the Papacy and other corruptors of God's truth, who stealthily introduce false doctrines into the church. He warns that this corruption has been ongoing and will culminate in a complete leavening of the truth, leading to widespread deception in Christendom. Ultimately, Pink calls for discernment and a return to the pure doctrine of Christ amidst the pervasive corruption.
