Even the unbeliever can't keep the law? Which is why they need Christ? So very true. What of the believer? Can be keep the law because he has Christ?Yes but even the unbeliever can not keep the law it’s why they need Christ
even so the law has fulfilled its purpose in the believer, thus is no longer needed
Matthew 23:23
“Woe to you, scribes and Pharisees, hypocrites! For you pay tithe of mint and anise and cummin, and have neglected the weightier matters of the law: justice and mercy and faith. These you ought to have done, without leaving the others undone.
So obedience is good, and ought always to be done, but there are more important aspects of life in Christ, as Jesus put it ‘weightier matters of the law’, which have a greater priority. Love, mercy, faith, justice. That Jesus said they are a part of the law is significant. There are those who claim the law was nailed to the cross: they have to reconcile the fact that love, justice, and mercy, (that is the gospel) , is part and parcel of that very law which they claim is of no further relevance to the Christian.
