Testing Jesus about his law—how bold is that? A Pharisees (social movement) lawyer (or expert in Moses’ law) posed a question to Jesus to put him to the test. 1 Corinthians 13 helps us understand why love is the supreme/royal law. Speaking in tongues, prophesying, knowledge, great faith, charitable giving, and martyrdom are nothing without love—love that never ends—it is the greatest of all things. God demonstrated this love—His royal law by giving us His son so that we can have eternal life.
