I agree. What I believe is, we should follow the OT commandments that the New Testament says apply to us. For example, of the 10 commandments, all of them are listed except for the Sabbath. That leads me to believe they are still binding in the New Covenant. (Romans 13:9 etc)
In other words: Should we steal today? Is stealing permissable for a Christian? No. Because the New Testament forbids it. Should we eat a kangaroo steak today? Not necessarily, but it is NOT forbidden to do so in the New Covenant.
2 Corinthians 3:5 Not that
we are sufficient of ourselves to think any thing as of ourselves; but
our sufficiency is of God;
If you had the capability of following OT commandments then the Lord Jesus wouldn't have had to sacrifice Himself on the Cross.
He could have just sent another prophet to tell the people to repent and follow the commandments.
2 Corinthians 3:6-8
6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
7 But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
8 How shall not the ministration of the spirit be rather glorious?
Galatians 2:19 For I through the law am dead to the law, that I might live unto God.
How can you be dead to the law if you are cherry picking what you think you should follow in the law and what you shouldn't? That's exactly what the Pharisees did.
Conversely you are not dead to the law and alive to God if you are stealing, murdering, worshipping idols, etc...
Proverbs 3:5 Trust in the Lord with all thine heart; and lean not unto thine own understanding.
That's hard to do, isn't it?
