All true Christians make themselves slaves of Christ voluntarily because they have tasted the wonderful fruits of that slavery. He never abolished either. Let us, therefore, be wise in not judging the Word but in understanding it in its great and glorious historical context. The Scripture must not be twisted to fit our pre-conceived doctrines and ideas. These days Christians move between denominations when it suits them and show little in the way of commitment.
Churches continue to schismatize exponentially.
Not so with true Christianity. I believe, that with these keys of understanding, you will come to appreciate the glory and beauty of the Law of Moses in light of the New Covenant. Before the truth supposed contradictions evapourate. Without that honest approach, the Scripture will remain a sealed book, full of imagined contradictions and horror stories. The truth truly sets you free.
