I have been studying the Bible for over 50 years, I understand it completely. For 20 of those 50 years, I was privileged to read the writings of some of the most prominent Christian scholars of our time. There are no contradictions in the Bible. Many like yourself do not understand the implications of the New Covenant, the Gospel and justification by faith. If you want to refute what I believe, please do it with scripture, otherwise it is nothing but hot air.
What good does it do for someone to show you that your understanding forces the Word of God to be contradictive? You think the proper way to discern Scripture is by taking a single verse or passage out of its context, not to prove truth, but rather to prove what you THINK. It would appear you've been studying in this manner for many years, and yet you still cannot see how one verse out of context cannot prove a doctrine if it causes contradiction in another passage. I too have studied the Bible for a number of years and have sought greater understanding through not only the writings of Old, but also those who have a great more biblical knowledge than I have. After all the years of studying and cross referencing the Scriptures, with these aids, and many more, I learned many years ago that when anyone comes to an understanding that causes disharmony and contradiction it must be filed in the bin labeled UNSOUND BIBLICAL DOCTRINE, and we must not let our pride keep us from accepting truth.
