I think it would overwhelm anhyone to read a list of peopl in the Old Testaemen who were led by the Holy Spirit, and they all studied the Word, either by reading or from the preaching of the prophets and priests.
Now, you are fatally in error if you believe anyone who loves the law is a legalist. I believe legalists are those who blindly interpret the law as being all of w hat Moses wrote down. Many of them are trumped by grace. If you were to learn the enitre Word of God from Genesis, you would already be aware of this by the Holy Spirit.
Keep in mind the great apostasy began as soon as our Lord ascended to His throne.
It seems the grace touters who believe the law is evil are the most legalistic individuals who come into this forum.
No one, not a one, except our blessed Salvation, ever was able to abide by, that is live by the Law alone, and this is way we need Jesus Christ, for the Law in its inherent from God wisdom, points to Jesus Christ, as He, Himself, teache you, me and all who hear Him.
Believe Jesus Christ, and worship Him in spirit and truth and do not look for excuses other than His Blood for your errors. He loves you, I love you, and I believe all here love you, so do not be terrified of being obedietnt. Jesus completes the law, but, as He teaches, He did not abolish any of the laws, and anyone who teaches against the least of them will be leasst in the Kingdom. Yes you live in grace, but that is no excuse to sin on purpos. Sin is breaking the law. Think aoubt that.
God bless you.
