Wow, so this would mean.... since nowhere in the Bible
(from jesus words or anywhere else)
are wives told to do the dishes,
then I dont have to ever do them again!!!
Seriously though, I do have a few opinions here. One specific area I have had issues with are Pauls teachings of women being silent in church, wearing head coverings, men with long hair, etc.
Over the years I have prayed and done research, asked pastors, etc. What I have learned is that Paul was specificaly talking to these particualr women, who had just come from idolatrous churches, they would stand up and shout questions and were rowdy and out of hand. For them, he said: "Be silent." This does NOT mean women should never speak a word in church.
As far as head coverings and men having to have short hair, I believe this also was a cultural thing. For that time, in that culture. If Paul were to be writing to a church in this day, he may say that we shouldnt take a mp3 player to church. Thousands of years from now that might confuse people.
As far as obedience to all areas of the Bible, one must study up. If we didnt study this, we might think we were to obey the Old Testament laws. There is much good to be learned from all areas of the Bible, and I believe that God inspired Paul, and all others in their writings. Teachings on taming the tongue and loving one another, how to treat our brothers and sisters in Christ.... these are things that most definitely should be done, yes. But by doing them we will not get to heaven. Jesus tells us plainly what we are to do. Believe in Him. After that, he gave some commands. Love the Lord your God with all your heart, mind, soul, strength.... and love one another.
So I believe that Jesus tells us what we must do to be saved. Failing, as we will, in other areas will not keep us out of Heaven, but most teachings and commands in the New Testament are for our benefit and should be followed as best we can.
In saying all this, I am assuming you are talking about obeying Jesus' words only, and not following the rest of the Bible. But in the event that this is not what you meant... are you meaning to say you will not obey any command unles Jesus stands in front of you literally speaking it?
