Sermon on the Mount, Matthew 5:27-32. Lust, adultery and divorce. These subjects can bring about a clearer understanding of the gospel. Big Idea: Marriage is a blessing not only because of the relationship with our spouse, but also because it helps us understand the gospel. Notes: Jesus tells us to not lose the main idea behind marriage, that it was intended to be "till death do you part". That means a lot of sacrifice and forgiveness which also means, We can get a glimpse of the love and grace we receive from the Lord.
