The sermon teaches that God's people should act with wisdom and initiative in light of His promises, while recognizing that even their best plans can be disrupted by the wicked—but God's sovereign plan can never fail. When famine strikes Canaan, Abram wisely goes to Egypt to preserve his household and devises a plan concerning Sarai that he believes will protect their lives and preserve God's promise, yet Pharaoh proves more wicked than Abram anticipated and seizes Sarai without negotiation or consent. Abram's wisdom can take him only so far, but when human plans fail, "the LORD" intervenes, striking Pharaoh's household with plagues, rescuing Sarai, preserving Abram, and ensuring that the promised seed will continue. The episode also foreshadows the later Exodus, when God's people again enter Egypt because of famine, suffer under a wicked ruler, experience God's judgment through plagues, and depart with Egypt's wealth. Ultimately, the sermon points to the cross, where Christ's enemies appeared to triumph, yet even their wicked actions accomplished what God had sovereignly determined beforehand. Our plans may fail and the plans of wicked men may temporarily succeed, but God's plans never fail, and His promises of salvation will always be fulfilled.
