The message, I beseech you, is found over 20 times in the Bible.
To beseech someone, is to beg, plead, or encourage them, to do a certain thing, or to live, think and act a certain way.
The first time we see it, is in Nehemiah 1.
The Prophet is reminding the people of the comands the Lord gave Moses.
That if they strayed, or transgressed, His commands, He would scatter them.
That was the Law, the Lord speaking.
We see the Grace of God, as always, available if we miss the mark of the Law.
If you turn to Me, and keep my commandments, (and do them), even if you have been cast out.
I will gather you again.
In the New Testament, we find Paul as the messenger.
He encourages us to walk worthy, of our calling, (Ephesians 4:1 and Thessalonians 4:1). To walk pleasing to God.
In (Romans 12:1), Paul he gets more specific, that we would:
present our bodies a living sacrifice, holy, acceptable unto God, which is our reasonable service.
The message of God is simple.
~ Love God and one another.
~ To walk worthy of, pleasing to God.
~ Be Holy, sacrifice our desires, and wants, to please God, more than ourselves.
We then hear the direct and practical voice of Peter.
There is not any question to his directive, in (1 Peter 2:11-12), that we:
abstain from fleshly lusts, which war against the soul; have honest coversatins with others, to draw them to God.
A final word from Paul. (2 Corinthians 6:1),
that ye receive not the grace of God in vain.
We know the desires of the Lord, now walk in them. Amen
