Mike Bickle emphasizes the significance of the seven parables of the kingdom found in Matthew 13, which reveal the true nature and expectations of God's kingdom. He explains that these parables were given to correct the misconceptions held by Israel about the kingdom's immediate glory and power, highlighting instead the importance of small, unseen works of God. Bickle warns against the dangers of having wrong expectations that can lead to offense and discouragement, urging believers to recognize the value of faithfulness in small things. He reassures that God's plan is intentional and that the kingdom will ultimately grow and flourish, even if it starts small and hidden. The sermon calls for a realignment of hearts to trust in God's leadership and to embrace the hidden treasures of the kingdom.
