Repentance
The true understanding of the above is to help use with our inner lives.
Jesus Christ preached that the kingdom of heaven is near and brought us the way of repentance, we should not just repent with our lips but truly hate sin from the depth of our hearts, and truly acknowledge that we will resist God because of our sins, and in our heart we are willing to repent before God.
Remember that we have received forgiveness of sins through the redemption of the Lord, but can we gain God’s forgiveness forever if we continue to sin, God’s mercy and tolerance are not rare, man’s true repentance is, God’s mercy and tolerance are not at all difficult to obtain; what is required is one’s true repentance above all.
Act 3:19 So we should repent then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord.

My understanding of repent means to change or to have a change of mind, and this change of mind involves both a turning from sin and a turning to God. This change of mind is a change of attitude and mental perspective, which results in a change in behavior. Repentance means to surrender one’s life—one’s whole being, both mind and body—to God’s will as expressed in His revealed Word.
On the positive side, repentance means turning to righteousness through a life of faith and obedience, the opposite of sin and disobedience. Repentance entails putting away the sinful activities defined by the commandments, and adopting the wholesome attitudes and behaviors of the positive side of God’s law, and repentance begins with a change of mind and results in a change of conduct too. Amen

Forgiveness
Is not always easy at any stretch of imagination, at times, it feels more painful than the wound we suffered, to forgive the one that inflicted it, and yet, there is no peace without forgiveness in our hearts, I believe forgiveness is the best form of love in any situation, it takes a strong person to say they're sorry and an even stronger person to forgive, when we forgive, you in no way change the past - but you sure do change the future.
Scripture tells us that in Ephesians 4:26-27 Be angry and do not sin do not let the sun go down on your anger, and give no opportunity to the devil, be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you, do not rejoice when your enemy falls, and let not your heart be glad when he stumbles, but strive for peace with everyone, and for the holiness without which no one will see the Lord.
In James 1:19-20 know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; for anger of a man does not produce the righteousness of God.
And also we must remember that our lack of forgiveness makes us hate, and our lack of compassion makes us hard hearted, and pride in our hearts makes us resentful and keeps our memory in a constant whirlwind of passion and self pity. Amen

Renounce
We must all renounce at sometime in our life all superficiality, all convention, all vanity and delusion in our time of life, but is that easy? Scripture reads that we have all become like one who is unclean, and all our righteous deeds are like a polluted garment. We all fade like a leaf, and our iniquities, like the wind, take us away.
I am aware that some people think that they never sin, let me ask these questions of you, personally, do you regularly and consciously sin, do you commit what you are convinced is sinful, without a determined effort to avoid it, do you do wrong with the full consciousness that this violates what God would want of you, do you have a careless attitude toward certain sins even though you are aware that they are sinful and hurt the heart of God and others.

Renounce Bad language
Most people know when they use bad language of various kinds, and they should know that it's a sin. But others use profanity by taking God’s name or Christ’s name in vain or taking these names in a careless or thoughtless way, some people use such words in nearly every sentence or maybe every several sentences in their conversation.
Scripture is quite clear about this. We are to put aside “malice, slander, and abusive speech from your mouth and renounce all for a better life.
Renounce fornication Some of us may think that everyone knows that fornication is sinful, but there may be a few people out there who are not as fully conscious of this fact as others.
Some also commit fornication or sexual immorality and know it is sinful and displeases God, but they go ahead and follow their flesh anyway.

Renounce
Anger again how often this sin is committed in the world around us! We suspect that nearly everyone knows that anger is sinful, except for instances of anger directed against sinful behavior renounce all anger it will lead you to a better life and a better understanding.

Renounce
Lying Lips also as sadly, we know that most people admit that they sometimes or regularly lie. A lie is deliberate telling an untruth. It is “a false statement made with deliberate intent to deceive; a falsehood.
The Lord Jesus said that a “false witness” comes “out of the heart” and thereby defiles the man (Matthew 15:19-20).
Deceit likewise comes from the heart (Mark 7:21-23).
We read that lying lips are an abomination to the LORD, but those who deal faithfully are his delight.
He also wrote, do not lie to one another, since you laid aside the old self with its evil practices (Colossians 3:9).
Nearly everyone who claims to be a follower of the Lord Jesus knows that God wants us to seek His will and His truth through His inspired Word.
We all know that God’s Word is “inspired by God” and “profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work” (2 Timothy 3:16).
But we fail to receive teaching based on Scripture, we refuse to be admonished by reproof from Scripture, we reject the correction of Scripture, and we are indifferent toward being trained in Scripture. I hope the read above has inspired you, and have changed you for a better person of different and better understanding. Amen
