Isaac is a picture of Christ in at least three ways. His birth was promised in advance, just as Moses and the prophets promised the coming of Christ. Isaac’s birth to ninety-year-old Sarah was a miracle, just as Christ’s birth to the virgin Mary was a miracle. Isaac’s father was willing to sacrifice him for the good of the world, just as God the Father accepted the sacrifice of his Son for the good of the world. It stands to reason, then, that the bride of Isaac should in some way resemble the Bride of Christ, the Holy Christian Church.
Abraham sent a servant to find a wife for his son Isaac and bring her to him. So also God sent prophets to prepare the way of the Lord, so that believers in the coming Savior were rescued by the same faith in Jesus that rescues Christians today. The apostles were sent to make disciples of all nations, and missionaries are still sent into the world, so that the Church will consist of people “from every nation, from all tribes and peoples and languages” (Revelation 7:9).
Abraham’s servant prayed to God for help. Those who preach and proclaim God’s Word do not save sinners by their own words of persuasion. Only Jesus saves sinners; only the Holy Spirit creates saving faith through God’s Word. The servant brings the message, but only God can provide the answer.
God answers the servant’s prayer “before he had finished speaking” (Genesis 24:15). The timeless God knows what we need and what we will pray. He wants us to pray, to keep in touch with him, but he generously provides for us—even more than what we ask—because of his love for us. Missionaries sometimes find that people who never heard of Jesus or the Christian Church are somehow prepared for the message, coming to faith as soon as they learn of the person and the work of Jesus Christ.
Abraham’s servant places jewelry from Abraham upon Rebekah before he speaks to her about marrying Isaac. The members of the Christian Church are not saved from sin and evil by the good things they do for God; they are saved by the good things Jesus has done for them. We bring nothing of our own to be accepted by Jesus as his people; we bring only the works Jesus has done for us—his obedience to his Father’s will, his sacrifice on the cross as a Ransom for us, and his victorious resurrection from the dead, defeating all God’s enemies on our behalf.
Rebekah is offered no choice whether or not to be married to Isaac. The servant describes his message from Abraham, Laban and Bethuel declare that “the thing has come from the Lord; we cannot speak to you bad or good. Behold, Rebekah is before you, take her and go, and let her be the wife of your master’s son, as the Lord has spoken” (Genesis 24:50-51).
Yet after she has been claimed as Isaac’s bride, she is given a choice whether she will linger in her old way of life for several days or whether she will leave immediately with Abraham’s servant to be brought to Isaac. We cannot choose to come to faith, for we were “dead in the trespasses and sins in which [we] once walked, following the course of this world” (Ephesians 2:1-2). God made us alive, giving us faith—much as the command of Jesus made Lazarus alive and able to walk out of his tomb (John 11:43-44). Being made alive, we can linger in our old sinful ways or live in the new life provided by God’s Gospel. The prophets and apostles frequently urge people not to linger in the darkness but to walk in the light. People who are alive have freedom to make good choices or bad choices. People who are dead have no freedom.
Rebekah chooses to travel immediately to her husband, not to linger in her old way of life. So also the Bride of Christ comes to him, to the husband who “might sanctify her, having cleansed her by the washing of water with the Word, so that he might present the Church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish” (Ephesians 5:26-27). Once again, Christians do not sanctify themselves for Jesus; they are sanctified by the work of Jesus, done on their behalf.
Before they left her home and her family, Abraham’s servant “brought out jewelry of silver and of gold, and garments, and gave them to Rebekah” (Genesis 24:53). When they approached Abraham’s home and Rebekah first saw Isaac from a distance, “she took her veil and covered herself” (Genesis 24:65). She came to her husband in clothing that he and his father had already provided to her. As God cast away the fig-leaf clothing Adam and Eve had made and provided suitable clothing for them, so the Church and its members come to Christ clothed in the righteousness he has provided us. “For as many of you as were baptized into Christ have put on Christ” (Galatians 3:27). Clothed in his righteousness, we are his Church. Today we are still engaged to Christ, waiting for the Bridegroom to come in all his splendor to bring us to his mansion. Already, though, we belong to him, chosen “before the foundation of the world” (Ephesians 1:4) to be his people forever.
