Mt 23:23...ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: .... strain at a gnat, and swallow a camel.

Of judgment, for God is righteous and He is the standard. We have nothing to boast about.

Of mercy, for God is merciful and we have nothing to despair about.

And the faith of all this, is faith in the person of God Himself.

We are allowed neither to boast nor to despair.
