Do a study on that and you will find that speaks of certain unbelievers.
It's speaking of those that once had the knowledge of God... so this is speaking of those that were born again but turned away from the Lord and chose to not retain the knowledge of God, and so the Lord turned them over to a reprobate mind and thei9r understanding became darkened
There are many who appear to be Christians... that have been turned over to a reprobate mind and many that are preachers too!
If Jesus had intended His followers to stop obeying the 10 Commandments, we would not have record of them obeying them after His death in Luke 23:54-56.
And yet... one of the 10 Commandments are NOT something New Testament believers are requited to follow and that is.... keeping Saturday sabbath.
NO where in the New Testament are any teachings found instructing Christians to keep Saturday sabbath as being a requirement for salvation. Not one verse teaches this.
The other commandments we are to keep thru the empowering of the Holy Spirit living within... which is totally different than what they did under the Old Testament. (see Philippians 4:13 - I can do all things through Christ which strengtheneth me)
Hebrews 8:6
But now hath He obtained a more excellent ministry, by how much also He is the mediator of a better covenant, which was established upon better promises.
HE is speaking of Jesus, our High Priest under the New Covenant (New Testament)
