Repentance

"Repent, or else I will come to you quickly and will fight against them with the sword of My mouth." Revelation 2.16

Contrary to feelings like remorse, repentance has to do with intelligent actions or attitudes of obedience. First, acknowledge your sin, then hate it and, finally, abandon it permanently.

Sincere heart

"Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water." Hebrews 10.22

The Spirit of God weighs the heart and knows when it is pure and sincere or not. Because of this, David reached mercy before God. He found true repentance to reach salvation.

MERCY

"Have mercy upon me, O God, according to Your lovingkindness, according to the multitude of Your tender mercies, blot out my transgressions."     Psalm 51.1

David's sin was extremely serious. However, every sin is deserving of forgiveness, as long as there is sincere repentance. 
David obtained repentance and forgiveness because of his sincere confession.
Today, the same mercy is available to all those who seek it. 

ANGER

"Be angry, and do not sin; do not let the sun go down on your wrath, nor give place to the devil."       Ephesians 6.26-27

The world we live in does not allow us to be perfect. There are moments where we get angry. However, we cannot allow this anger to turn into grief. Before the sun goes down that anger must give way to repentance and forgiveness. 
By doing this, the devil will not find any gaps to enter into your life.

FORGIVEN

"Who shall bring a charge against God's elect? It is God who justifies."     Romans 8.33

When there is a sincere repentance, there will be true forgiveness. And when this happens, not even the devil, your conscience or anybody else has the right to continue accusing you. 
If the Holy Spirit has forgiven you, who can accuse you?

SINNER

"And the tax collector, standing afar off, would not so much as raise his eyes to heaven, but beat his breast saying, "God, be merciful to me a sinner!"    Luke 18:13

When you are sincere in acknowledging your sins and repent, you receive forgiveness, salvation and perfect inner peace.

THE SIN THAT BINDS

"He who covers his sins will not prosper, but whoever confesses and forsakes them will have mercy." Proverbs 28:13

Although we may hide our sins from everyone around us, we can never hide them from God or from the devil. The success of many Christians has been blocked because their sins have left them in debt with the devil. But when you confess and forsake your sins, Jesus forgives you and opens up the door that leads to prosperity.

Grafted Again

“…if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.” Romans 11:23
 

If the one who fell stops listening to the voice of doubt and start hating the sin that separates him from God, he will receive the gift of repentance and will go back to the Way. The Holy Spirit will graft him back to the Root of David and make everything new.

There’s still time

“And I gave her time to repent of her sexual immorality, and she did not repent.” Revelation 2:21

The voice of the Holy Spirit calls to repentance those who are living in sin.

There’s still time to start over.

Repentance is not a feeling. It’s an attitude, it’s a decision, it’s courage to turn from sin once and for all and return to the practice of faith. Each person is convicted by the Holy Spirit if he is living or not in sin.

The Gift

"Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit." Acts 2:38 

Every action results in reaction. Repentance is not a feeling, but an attitude of abandoning sin. Then comes forgiveness from God and the gift of the Holy Spirit.

The Lord's Servant

"And the Lord’s servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil, correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth." 1 Timothy 2:24-25

Those who are in the faith have been evangelizing the unbelievers with wise, patient and gentle words, so that they may be led to the knowledge of life in the Lord Jesus and His powerful Word, resulting in repentance of sins.
