This rebellion against God is so pervasive in entertainment and culture that some believers are susceptible to the idea that it is a small issue that we need to flex upon in order to have influence with others.
But, for those who are genuine Christians, there is no room to flex.
Matthew 19:4-6 And [Jesus] answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.”If we can't trust that Jesus is right about the basis of marriage in the creation, the purpose of marriage in joining one man to one woman, and the nature of marriage as a covenantal joining conducted by God Himself...
...then why would we trust that Jesus is right about the basis, purpose and nature of His cross?
We trust Him about our eternal salvation and blessing. Let us also trust Him about this great earthly blessing of marriage.
