The readings today call us: Choose this day whom you will serve? This choice cannot be ala carte - picking and choosing what we want and rejecting what we don’t want. Because everything Scripture teaches connects back to Jesus. It is personal. We are choosing or rejecting him. 
This is important when we look at many of the “issues” of our day around the topics of gender, marriage, and sexuality. They are not isolated issues. They are personal because they are all connected to him.  As Pauls writes: 
“Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.” This mystery is profound, and I am saying that it refers to Christ and the church. (Ephesians 5:31–32)

We must choose whom we will serve and love. 
Marriage and sexuality image God and his relationship with us.
