How is something an external command if Jesus tells us to do it?
The New Covenant maintains the commandments of the Mosaic Covenant (Old Covenant).
God's commandments will never cease.
Matthew 7:21
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mark 3:35
For whoever does the will of God is My brother and sister and mother."
John 14:15
15“If you love Me, you will keep My commandments.
Psalm 119:89
Your word, O LORD, is everlasting; it is firmly fixed in the heavens.
The law has passed away...the Law of Moses...
But the Word of God, the Commandments...
will live forever.
I don't understand what you're saying.
First you say that The New Covenant maintains the commandments of the Mosaic Covenant (Old Covenant). Then you say that the law has passed away...the Law of Moses... These are contradictory statements.
Since we are
in Christ and He kept the requirements of the OT law perfectly, then we are considered to have kept them perfectly.
The OT law does not apply to Christians.
The Word of God, the Commandments, will live forever. But they apply only to those who are outside of Christ.
Paul wrote this to the church in Galatia regarding the OT law... "For freedom Christ has set us free. Stand firm, therefore, and do not submit again to a yoke of slavery" Galatians 5:1.
It is preceded by this great symbolic passage...
"Tell me, you who desire to be subject to the law, will you not listen to the law? For it is written that Abraham had two sons, one by an enslaved woman and the other by a free woman. One, the child of the enslaved woman, was born according to the flesh; the other, the child of the free woman, was born through the promise.
Now this is an allegory: these women are two covenants. One woman, in fact, is Hagar, from Mount Sinai,
bearing children for slavery. Now Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.
But the other woman corresponds to the Jerusalem above; she is free, and she is our mother. For it is written,
“Rejoice, you childless one, you who bear no children,
burst into song and shout, you who endure no birth pangs,
for the children of the desolate woman are more numerous
than the children of the one who is married.”
Now you, my brothers and sisters, are children of the promise, like Isaac. But just as at that time the child who was born according to the flesh persecuted the child who was born according to the Spirit, so it is now also. But what does the scripture say? “
Drive out the enslaved woman and her child, for the child of the enslaved woman will not share the inheritance with the child of the free woman.” So then, brothers and sisters,
we are children, not of an enslaved woman but of the free woman." Galatians 4:21-31
BTW, I hope that Free reads this! Perhaps he will gain some understanding of the law vs freedom. But I'm not hopeful. 8^(
