Hi Five Solas. Good afternoon. Chr-stians have rejected the Law. They reject the seventh day Sabbath, which is Friday night to Saturday night, as Yahshua kept it, as do the Jews. They reject the dietary laws. The holy days. The Sacred Name(s) also thus rejecting the third commandment. And many other laws in the Hebrew Scriptures. You mentioned the will of Yahweh. The scriptures say "15 Look therefore carefully how you walk, not as unwise, but as wise; 16 redeeming the time, because the days are evil. 17 Therefore be not foolish, but understand what the will of Yahweh is." The will of Yahweh has always been and will always be that we keep His commandments. Not some of the commandments, but all of them. If we desire the Holy Spirit, which is Yahweh's character embodied in us, we have to keep His Law, which contains His personality.
In terms of what you are saying about not being able to obey the law perfectly, perfection is something we strive for as stated by Yahshua in the Sermon on the Mount in Matthew 5:48 "Ye therefore shall be perfect, as your heavenly Father is perfect." and with the help of the Holy Spirit we can overcome and reach a state well-pleasing to Yahweh.
If you read over your post, you should be able to see that there is some confusion in your thinking. Paul says: "But I fear, lest by any means, as the serpent beguiled Eve in his craftiness, your minds should be corrupted from the simplicity and the purity that is toward the Messiah" Eve was instructed not to eat the tree of knowing good and evil. That was a commandment. Just as we are commanded to do the good by keeping His Law and not know the evil. Those who have done evil in the past, can recover themselves through Yahshua and change their ways. Any excuse to not keeping all of the Laws comes from Satan, just as it did with Eve. The message is simple and it is apparent throughout the whole Bible: Keep the commandments.
Ecclesiastes 12:"13 Let us hear the conclusion of the whole matter: all has been heard: fear Elohim, and keep his commandments; for this is the whole of man. 14 For Elohim will bring every work into judgment, with every hidden thing, whether it is good, or whether it is evil."
