Galatians 3:27-28, …for in Christ Jesus you are all sons of God, through faith. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. Peter was very much in touch with reality. He knew that marriages couldn’t be realized as a “heaven-on-earth” manifestation. Marriages, similar to other institutions, suffer from the adverse result of mankind’s fall. Because every marriage will experience suffering and groaning, Peter assumes that even the marriages of Christians who live godly lives will endure suffering. As a result of this fallen world, and our sinful nature, Christian marriages are susceptible to the same ailments found in non-Christian marriages.
