After Jesus was baptized in the Jordan river by John the baptist, immediately the Holy Spirit came on Him. The first thing Jesus preachers after His wilderness experience was ‘Repent for the kingdom of God is at hand’ ( Matt 4:17 ). In Acts 2:38 The Apostle Peter stood up after the Holy Spirit filled him and preached ‘Repent, and be baptized in the name of Jesus Christ for the remission of your sins, and you shall receive the gift of the Holy Spirit.
Some will say that this repentance was for the Jews to turn from the works of the law of Moses and do it your self religion, to a faith in Jesus and being saved by grace. That is true, we do need to repent of dead works. But as we go on through the bible we see that there is a fuller understanding of repentance that it is not only for the Jews and from dead works but from all sin, both Jews and Gentiles. When Philip was in Samaria and preached Christ to them, many believed and were baptized in the name of the Lord, including Simon who practiced sorcery ( witchcraft ) ( Acts 8:12-13 ), but when we see the apostles come to fill the believers with the Holy Spirit that Simon offered money to the apostles to buy the gift of the Holy Spirit. Peter rebuked him, told him that his money perish with him, Peter then told Simon that his heart was not right in the sight of God and to repent of his wickedness and pray that God would forgive him ( Verse’s 19-23 ). Notice that this was a man who had believed in Jesus Christ and was baptized.
In Acts 17:15 we read that Paul is brought to Athens, as we read through the chapter we see that this Athenians were ignorant of God, the were idolaters. Then in verse 30 he said ‘Truly these times of ignorance God overlooked, but now COMMANDS ALL MEN EVERYWHERE TO REPENT. All men means all people Jews and Gentiles.
In Acts 26 we read that Paul is preaching to king Agrippa, Paul shares his testimony and in verse’s 19-20 Paul says that he was obedient to the heavenly vision and how he preached first in Damascus, Jerusalem, Judea and to the Gentiles, that they should repent, turn to God, and do works befitting repentance.
In 1 Corinthians 5 we read that Paul commands the church to hand the one who was committing sexual immorality over to satan for the destruction of his flesh. Now in 2 Corinthians 2:1-11 we see that Paul says that the punishment that was inflicted on him ( the man who was handed over to satan ) was sufficient for him and that they the church were to forgive him. In chapter 7:9-12 that the GODLY SORROW LED TO REPENTANCE WHICH LEADS TO SALVATION.
In chapter 12 of 2 Corinthians verse’s 20-21 Paul said that he was concerned that he would mourn for many who have sinned in Corinth and have not repented of there uncleanness, fornication, and lewdness which they have practiced.
In Revelation chapters 2 and 3 we read that the Lord Jesus is speaking to the church’s to repent in spite of all the good works they were doing. Most of the church’s had good works, endurance, hated those who were evil, tested those who said that they were apostles but were not, they held fast to His name, those who did not deny the faith, others had love, there last works were better than the first. And yet the Lord commanded them to repent or be punished. These letters are written primarily to the pastors of the churches. The Lord spoke to the pastor or messenger of the church at Thyatira to repent of allowing that women Jezebel. ( The original text says ‘your wife Jezebel’ ). The Lord said that He would cast her into a bed of anguish and those who commit adultery with her and kill her children unless they repent of there deeds.
So we can see from the word of God that we must live a holy clean life. Many other scriptures confirm this like 1 Corinthians 10:1-12 Paul speaks of Israel in the wilderness how they complained, tempted Christ, committed immorality, God destroyed those who did such things and Paul says that those things took place for our learning that we should not walk in that. Therefore let him who thinks he stands take heed lest he fall ( 12 ). In 2 Corinthians 5:9-15 we see that we must all appear before the judgment seat of Christ, Knowing therefore the terror of the Lord, we persuade men. (11 ) Those who live should no longer live for themselves, but for Him who died for them and rose again. ( 15 ) Therefore having these promises beloved LET US CLEANSE OURSELVES from all filthiness of the flesh and spirit, PERFECTING HOLINESS IN THE FEAR OF GOD. ( 7:1 )
