You first promised never to marry, but later you did so. Why?

Luther:

Because I made my promise mistakenly; I was misled by what the church taught. Marriage is necessary for almost everyone. When God says: ‘Be fruitful, and multiply’, then it is not just a commandment, but something that God also blesses. So, you cannot ignore that. It is as necessary as eating, drinking, washing, sleaping and being awake. It is in our nature that we have to multiply. When you want to ignore that then you will fail and it will not work and you will end up in harlotry, adultery and dumb sins. It is our nature; we cannot choose to ignore it by our own power.
