Not trying to be condescending, just honest. To me, the words saying you obey "not to murder" as something random or coincidence, instead of giving Glory to God for ALL things, including His laws that He personally wrote, seems disrespectful.You again misrepresent in a very condescending way.
Non Jewish Christians do indeed recognize the authority of God especially as expressed through the personification of the New Covenant, Jesus the Christ.
27 My sheep hear my voice, and I know them, and they follow me. 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. 30 I and the Father are one.”
His sheep hear His voice so when Jesus says, If you love Me, keep My commandments, His sheep obey.
There are not two salvations- one for the Jews one for Gentiles, there is only one. The New Covenant promise was not made with Gentiles, but if you are in Christ, you are grafted into the promise of the New Covenant. In the New Covenant God writes His laws in our hearts and minds Hebrews 8:10 and we should also obey out of love as it is a fruit of a saved person. God bless.
