We are cleared of all guilt and are justified by the grace of God(Titus 3:4-7) But after that the kindness and love of God our Saviour toward man appeared, Not 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; Which he shed on us abundantly through Jesus Christ our Saviour; That 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)And we know that all things work together for good to them that love God, to them who are the called according to [his] purpose. For 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. Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. What shall we then say to these things? If God [be] for us, who [can be] against us? He 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? Who 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) And 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. Either 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. O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. A 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. But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned.

Therefore being justified by faith, we have peace with God through our Lord Jesus Christ: By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God. (Romans 5:1,2).
