Therefore thus says the Lord [to Jeremiah]: If you return [and give up this mistaken tone of distrust and despair], then I will give you again a settled place of quiet and safety, and you will be My minister; and if you separate the precious from the vile [cleansing your own heart from unworthy and unwarranted suspicions concerning God’s faithfulness], you shall be My mouthpiece. [But do not yield to them.] Let them return to you–not you to [the people]. Jeremiah 15:19 (AMPC)
You who has heard, believed and settled in God’s love and faithfulness are now His mouthpiece. Through you God is reaching out and appealing to many more to join in this family of His beloveds.
According to 2 Corinthians 5:20 You are Christ’s ambassador; God is making His appeal as it were through you. As Christ’s personal representative you’re here on earth to persuade others to lay hold of the divine favor now offered to them and be reconciled to God.
Being God’s mouthpiece doesn’t mean just talking the talk without walking the walk.
It’s more than a vocal impersonal “thus says the Lord” It’s more so like a visual audio HD format daily lifestyle.
For instance, telling others about how God loves them without practicing and living it yourself before them is what James 2:17 calls faith without works – it is dead! It is unprofitable. James illustrates this point.
James 2:15-16 If a brother or sister is naked and destitute of daily food, and one of you says to them, “Depart in peace, be warmed and filled,” but you do not give them the things which are needed for the body, what [does it] profit?
Like He did to Jeremiah the Lord has put His message of love and life in our mouth.
Jeremiah 1:9(AMPC) Then the Lord put forth His hand and touched my mouth. And the Lord said to me, Behold, I have put My words in your mouth.
But more than that the Lord Himself, His Life, Love, Light dwells in us. He wants us to communicate Him, His Love, Life and Light to the others who are still languishing in the prison of destitution, darkness, and death.
As God’s mouthpiece we are an example, a pattern for others in what we say, the way we live, our love, our faith, and our purity-see 1 Timothy 4:12. Our act and attitude ought to attest to God.
