I am no musician, but I do have some understanding of what an amplifier is and what it does. The amp takes the sound of the guitar and makes it louder, clearer, and more noticeable. Some noises may not have been noticeable without the amp (even though they were still there) but are now expressed at a larger volume because of the amp. Other noises were very noticeable without the amp are made even more obvious and clear with the amp.
After two months and a few days of marriage I have learned that marriage is an amplifier. Our marriage has made my sin louder, clearer, and more noticeable. Some sin that was not as noticeable before marriage (even though it was still there) has become very noticeable. The selfish and self-centered heart I had before married life has become more evident in light of marriage.
I believe this is a good thing. It leaves me with two possible forms of action.
1. Keep and revel in my sin and serve myself.
2. Confess and repent of my sin and serve my wife.
Let me propose it would be best to take the second option instead of the first. Marriage creates opportunities for repentance. Marriage forces you to keep your sin, or confront your sin. Sin will be exposed in a godly marriage, but there will also be repentance. If sin is not being exposed in a marriage that is evidence the marriage is not centered on Christ.
Marriage being an amplifier is a very good thing not only because it makes obvious the sin I need to repent, but also because it amplifies my strengths and godly desires. Marriage has amplified my desire to follow Christ and make his name great. Marriage is a daily reminder of the Gospel. Marriage is a daily reminder to be like Christ. Marriage is a daily reminder that I am the bride of Christ.
Bear fruits in keeping with repentance. Luke 3:8 ESV
