We are cleared of all guilt and are justified by the grace of God(Titus 3:4-7).4But after that the kindness and love of God our Saviour toward man appeared,5Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;6Which he shed on us abundantly through Jesus Christ our Saviour;7That being justified by his grace, we should be made heirs according to the hope of eternal life.

Even though man in his own way thinks he has the power to justify the way he lives,it is the calling of God on a life who justifies a person in Christ(Romans 8:28-33).28And we know that all things work together for good to them that love God, to them who are the called according to [his] purpose.29For whom he did foreknow, he also did predestinate [to be] conformed to the image of his Son, that he might be the firstborn among many brethren.30Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.31What shall we then say to these things? If God [be] for us, who [can be] against us?32He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?33Who shall lay any thing to the charge of God’s elect? [It is] God that justifieth.

It is written a tree is known by its fruit and by the words we speak we are justified or condemned(Matthew 12:32-37).32And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the [world] to come.33Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by [his] fruit.34O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.35A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.36But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.37For by thy words thou shalt be justified, and by thy words thou shalt be condemned.

“Death and life are in the power of the tongue:and they that love it shall eat the fruit thereof”(Proverbs 18:21).
