David Wilkerson emphasizes that while there is a significant cost to being fully committed to God, the rewards far outweigh the difficulties. He illustrates this through the example of Moses, who, despite being filled with God's revelation and excitement for deliverance, faced rejection from his own people. Wilkerson points out that a true hunger for God often leads to misunderstandings and distance from friends and family, as they may not comprehend the depth of one's spiritual journey. Ultimately, the greatest reward for unwavering faith is the constant presence of Christ, which surpasses all earthly challenges and misunderstandings.
