For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. - John 3:16

Confessing Your Sins

It is impossible to please God and be saved without confessing your sins. The word confess simply means: tell, acknowledge to God, declare faith in, and admit one's faults. “That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.” (Romans 10:9)

Repentance is a turn from sin to God

To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. Whereupon, O king Agrippa, I was not disobedient unto the heavenly vision: But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance. (Acts 26:18-20)

It has three necessary aspects: an intellectual change (change of views), and emotional change (change of feelings), and a volitional change (voluntary change of purpose). It includes recognition of sin (Mark 2:17)When Jesus heard it, he saith unto them, They that are whole have no need of the physician, but they that are sick: I came not to call the righteous, but sinners to repentance., confession of sin to God (Proverbs 28:13;He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy. I John 1:9),If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. contrition or godly sorrow for sin (Psalm 51:17;The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise. II Corinthians 7:10), For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death. and a decision to forsake sin (Proverbs 28:13).He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

Then said he to the multitude that came forth to be baptized of him, O generation of vipers, who hath warned you to flee from the wrath to come? Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham. (Luke 3:7-8)
With repentance comes the willingness to make restitution for past sins as much as possible (Matthew 5:23-24;Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee; Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift. Luke 19:8).And Zacchaeus stood, and said unto the Lord: Behold, Lord, the half of my goods I give to the poor; and if I have taken any thing from any man by false accusation, I restore him fourfold.

Repentance is the first response to faith to the call of God (Mark 1:15).And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel. It is absolutely necessary to salvation (Luke 13:5;I tell you, Nay: but, except ye repent, ye shall all likewise perish. Acts 17:30,And the times of this ignorance God winked at; but now commandeth all men every where to repent: II Peter 3:9).The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.

I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:3)
Without repentance baptism is not effective, and without repentance a person cannot receive the Holy Spirit (Acts 2:38).Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. (Acts 3:19)

At repentance, a person begins to let God work in his life. He decides to turn away from sin and allows God to turn him. As part of the turn from sin, God enables him to break away from sinful habits and desires. As part of the turn to God, repentance prepares the way for him to have a personal relationship with God, qualifying him for baptism of water and Spirit.

The work of forgiveness and remission comes through repentance and water baptism (Acts 2:38).Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. Repentance deals with a person’s sinful lifestyle, and baptism deals with the record and consequences of sin.
