This sermon explores the unexpected call of God through the example of Mary. It emphasizes that God does not call the qualified but qualifies those He calls, inviting believers to say YES to four key aspects: the real self, the gift of God, His purposes, and trusting Him. Mary’s example demonstrates faith and obedience in the midst of uncertainty, showing that God’s call is both challenging and good. Believers are encouraged to recognize God’s favor, embrace His purposes in knowing and making Jesus known, and trust Him fully, even when circumstances seem impossible.
