brother Christ and the gospel is Gods standard of righteousness Moses law has absolutely nothing to do with it that’s why thre apostles all agreed it’s not Christian doctrine in acts 15 when the question arose
the law is how sinners hear from God it’s not for the righteous
“Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;”
1 Timothy 1:9-10
It’s how those folk saw Gods word “ don’t do this or die , don’t do this or die ect that’s not righteous to simply not kill or steal that’s a sinner restraining thier sin from fear
righteousness is only found in the gospel Jesus taught in fact he himself is the shown standard of Gods righteousness has nothing to do with and is seperate from the law
“But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:”
Romans 3:21-22 KJV
In other words atheists often don’t kill , steal , lie and cheat but it doesn’t make them right with God , not killing is one thing but helping others tangibly laying our own selves down to help another in need is another
the law is for sinners trying to obey a list of rules and restrain the sin living in them , Christians however belong to the renewing of the mind that comes from the gospel not for lost sinners but for repentant children of God
not killing is t what’s going to save us loving God and others through Jesus Christ and his word will
