Colossians 4:6. Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.
Matt 12:34. Brood[a] of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks.
Proverbs 4:23. Keep your heart with all diligence, For out of it spring the issues of life.
Proverbs 10:11 The mouth of the righteous is a well of life, But violence covers the mouth of the wicked.
Psalm 14:1. The fool has said in his heart, “There is no God.” They are corrupt, They have done abominable works, There is none who does good.
Proverbs 24:12. If you say, “Surely we did not know this,” Does not He who weighs the hearts consider it? He who keeps your soul, does He not know it? And will He not render to each man according to his deeds?
Let your speech be always with grace,…. “In grace, or concerning grace”: let grace be the subject matter of your speech and conversation. When saints meet together they should converse with each other about the work of grace upon their souls, how it was begun, and how it has been carried on, and in what case it now is; they should talk of the great things and wonders of grace, which God has done for them, which would be both comfortable and edifying to them, and make for the glory of the grace of God; and also, they should confer together about the doctrines of grace, and so instruct, establish, and build up one another in them; and at least their conversation should always turn on things graceful and acceptable, such as may minister grace unto the hearer, and be useful and edifying; wherefore all obscene words, unchaste expressions, filthiness, foolish talking, and jesting, ought not to be used. Or this may regard the manner of the speech, and language of the saints; it should be in the exercise of grace; it should be in truth, faithfulness, and sincerity, without lying, dissimulation, and flattery; it should be in consistence with the grace of love, therefore evil should not be spoken one of another; nor should there be whisperings, backbitings, or anything said that is injurious to the character, credit, and reputation of another; for this is contrary to love, and so not with grace: and whatever is said should be spoken in the fear of God; the reason why so many evil things proceed out of the mouths of men is, because the fear of God is not before their eyes. Moreover, the speech of the saints ought to be in a graceful way, with a cheerful and pleasant countenance, in an affable and courteous manner, and not after a morose, churlish, and ill natured fashion: and this should be “alway” the case; not that they should be always talking, for there is a time to keep silence, as well as a time to speak; but the sense is, that when they do speak, it should be both graceful things, and in a graceful manner; so that there is never any room and place for vain discourse, unprofitable talk, and idle words, which must all be accounted for in the day of judgment.

There is way too much influence from the world in our hearts and minds in regards to being able to speak with grace and wisdom. First, the food which feeds the heart is what comes out of the mouth. “For out of the heart the mouth speaks.” Second, we are to be mindful of our hearts. “Keep your heart with all diligence.”
What are we allowing into our hearts? How does it get there? The answers to these two questions are quite simple. What is it that you are feeding your heart with? Is it the Word of God, or things of this world? The scourge to the heart of most believers comes from the world. Social media, news outlets, and other articles not only influence but consume the hearts of those who approach being a believer as a singular means to eternal life rather than endless reasons to honor and glorify Jesus Christ in all thoughts, words, and actions.
What we put into our hearts will affect our thoughts, words, and actions
