Paul poses a thought-provoking question to the Galatians, urging them to consider the source of their spiritual experience. He contrasts two ways of receiving the Holy Spirit: through the works of the law or by believing the message of Christ. This distinction highlights a central theme in Christian theology: salvation and the presence of the Holy Spirit are gifts received through faith, not earned by human effort or adherence to religious rules.
By asking this question, Paul reminds the Galatians—and all believers—that the core of the Christian faith is trust in the gospel message. This trust leads to a personal relationship with God, marked by the indwelling of the Holy Spirit. It underscores the idea that faith, rather than legalistic observance, is the true path to spiritual fulfillment and growth. This message is a call to focus on the transformative power of faith, encouraging believers to rely on God's grace rather than their own merits.
