What are the consequences of the curse attached to the law of Moses? [3rd of 3 questions on this topic]

***This might usefully take us back to what the [first question in this series](https://christianity.stackexchange.com/q/107548/10672) pointed to – Paul’s explanation to Christians*** in Galatians 3:10-12. That last verse is connected to Leviticus 18:5. And perhaps 1 Peter 3:18 might show God’s plan of saving humanity from this curse of the law. But I don’t want to cramp your answers, just so long as they actually stick to the confines of this last series of questions – if you don’t mind! Is it reasonable to suggest that justification cannot be obtained through human efforts; that faith in the work of Christ avails for salvation, and that reliance to any degree on works excludes trust in the finished work of Christ? This question is scoped for any Christians who believe perfect obedience to God’s laws are the goal all Christians should, and could, aspire to, to be justified; but as there may be very few such individuals on this site, to also seek answers from those who say such a thing is impossible, but that there are aspects of God’s law Christians must follow, albeit not with salvation in view, but to please and honour him.
