I get the distinction, but the sending of the Spirit on Pentecost is evidence that a new covenant is in effect. Also, Hebrews states as much. And the epistles are all about how to live under such a covenant.
31 He told them another parable: “The kingdom of heaven is like a mustard seed, which a man took and planted in his field. 32 Though it is the smallest of all seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds come and perch in its branches.”
This is what scripture says, it is evident that not all, far from it, follow the commandments. it is Why this is proof the new covenant is not in effect yet . A covenant is an agreement between 2 parties, many do not want to follow the commandments, there is no covenant at this time but soon, when out Lord and Savoir returns he will make this covenant with his people.
Blessings.
