In this sermon, Pastor Chad Kettler traces the biblical narrative of God's promise to bless all nations through Abraham and his offspring. Though Israel failed in its mission to represent God and bring blessing, Jesus Christ fulfilled this role as the ultimate Son of Abraham. Jesus accomplished what Israel could not by perfectly keeping the law and willingly dying on the cross to bear the curse for sin, so that through faith in him all people can receive the promised blessing of righteousness and eternal life. Kettler emphasizes that law-keeping and good works cannot make anyone righteous - the only way is through faith in Christ, who endured the curse of sin so that the blessing promised to Abraham would come even to the Gentiles. The sermon calls for renewed joy and celebration in what Christ has accomplished for sinners through his death on the cross.
