1:5-11 Whatever tends to weaken love to God, or love to the brethren, tends to defeat the end of the commandment.

And as believers were righteous persons in God's appointed way, the law was not against them. But unless we are made righteous by faith in Christ, really repenting and forsaking sin, we are yet under the curse of the law, even according to the gospel of the blessed God, and are unfit to share the holy happiness of heaven.
