Martin Luther is often quoted as using his baptism as a weapon in his battles with the devil. “I have been baptized,” he would tell the devil in order to make him flee. Who God told him he was and what God promised him in his baptism was Luther’s anchor that kept him moored so that he would not be ultimately dashed to pieces by the virulent waves of doubt that assaulted his soul.
We may not generally resort to our baptism as Luther did, but we should. We shouldn’t be afraid of the water. In baptism God told us that we belong to him. In baptism God united us to his Son in the church. We have been anointed with the Spirit with whom Jesus, our Head, was anointed in his baptism and ultimately his coronation. Luther was doing nothing that Paul himself didn’t do when dealing with the churches. In 1Corinthians 12 Paul appeals to their baptism to fight the factionalism in the church. Similarly in Galatians 3 Paul tells the Christians of Galatia that all those who have been baptized into Christ have put on Christ–whether Jew or Greek, slave or free, male or female–and all are the seed of Abraham and heirs according to God’s promise. In Romans 6 Paul uses baptism to encourage the Roman Christians that sin no longer has dominion over them. Peter also uses baptism to assure the Christians scattered throughout the Empire that they have a good conscience before God through the resurrection of Jesus (1Pt 3.21). The writer of Hebrews speaks about us being washed with pure water and, therefore, having boldness to draw near to God (Heb 10.22). When we look to our baptism, we are not looking to mere water or believing in some sort of hocus pocus. We are looking to what God said about us. We are looking to his Word that he sealed to us in the water by his Spirit. This is why the writers of the Scriptures can appeal to it the way they do and exhort people to walk in faithfulness according to their baptism.
This week as you go through the daily routines of life and/or face some unusual circumstances, you do so as a person who has been baptized into the Triune name. You face whatever you face as someone whom God has claimed for himself and promised that he is working every circumstance for your salvation. You know, therefore, that whatever you face, whether it be good or ill, God is in it working for you and not against you. The call to you is to walk in faith, trusting what God said about you. The call to you is to live like a baptized person ought to live; whether in unity with your brothers and sisters in Christ or resisting the other sins that no longer have dominion over you. Whatever it is, you can stand firm in the waters of your baptism because there God has given you his word.
