Exactly. The law is still relevant, but it must be understood spiritually for God is a Spirit, and the persuasions in God's word are those things that motivate us into action according to His will.

We then should study "all" of God's word, including the law He gave to Moses, and see the spiritual motivation of His will for us. Jesus Christ came to change us, He didn't come to change what cannot be changed and established by His own Father. The problem that causes adversity in the ranks of the church is that some false doctrines want to change the Word and blind us to the fact that Christ came to change us through faith in Him.
"Be not carried about with divers and strange doctrines. For it is a good thing that the heart be
"established" with grace; not with meats, which have not profited them that have been occupied therein." Hebrews 13:9
