I would say that the majority of the Christian faith still believe they are sinners even though they have repented and are baptized into the Name of Jesus. This is a very sad state to which the church finds herself as she has believed the lie rather than God. Acts 3:14 But you denied the Holy One and the Just, and asked for a murderer to be granted to you, 15 and killed the Prince of life, whom God raised from the dead, of which we are witnesses. 16 And His name, through faith in His name, has made this man strong, whom you see and know. Yes, the faith which comes through Him has given him this perfect soundness in the presence of you all. 17 “Yet now, brethren, I know that you did it in ignorance, as did also your rulers. 18 But those things which God foretold by the mouth of all His prophets, that the Christ would suffer, He has thus fulfilled. 19 Repent therefore and be converted, THAT YOURS MAY BE BLOTTED OUT, so that times of refreshing may come from the presence of the Lord, 20 and that He may send Jesus Christ, who was preached to you before, 21 whom heaven must receive until the times of restoration of all things, which God has spoken by the mouth of all His holy prophets since the world began.
Have you repented and turned from sin as Jesus has said; John 5:14 Afterward Jesus found him in the temple, and said to him, “See, you have been made well. Sin no more, lest a worse thing come upon you.” John 8:11 She said, “No one, Lord.” And Jesus said to her, “Neither do I condemn you; go and sin no more.”
Are you saved from sins? This is what Jesus’ purpose was to save people from their sins. Do you believe this? Are you a believer of this? Matthew 1:19 Then Joseph her husband, being a just man, and not wanting to make her a public example, was minded to put her away secretly. 20 But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit. 21 And she will bring forth a Son, and you shall call His name Jesus, for He will save His people from their sins.”
Once you know the truth and He has set you free from sin, you get to out and forgive others of sin. If you confess that you are still a sinner and haven’t been forgiven of sin, how the do you forgive others when you haven’t been forgiven? Luke 7:47 Therefore I say to you, her sins, which are many, are forgiven, for she loved much. But to whom little is forgiven, the same loves little.” 48 Then He said to her, “Your sins are forgiven.” 49 And those who sat at the table with Him began to say to themselves, “Who is this who even forgives sins?” 50 Then He said to the woman, “Your faith has saved you. Go in peace.” Matthew 9:4 But Jesus, knowing their thoughts, said, “Why do you think evil in your hearts? 5 For which is easier, to say, ‘Your sins are forgiven you,’ or to say, ‘Arise and walk’? 6 But that you may know that the Son of Man has power on earth to forgive sins”—then He said to the paralytic, “Arise, take up your bed, and go to your house.” 7 And he arose and departed to his house. 8 Now when the multitudes saw it, they marveled and glorified God, who had given such power to men.
Acts 11:12 Then the Spirit told me to go with them, doubting nothing. Moreover these six brethren accompanied me, and we entered the man’s house. 13 And he told us how he had seen an angel standing in his house, who said to him, ‘Send men to Joppa, and call for Simon whose surname is Peter, 14 WHO WILL TELL YOU WORDS BY WHICH YOU AND ALL YOUR HOUSEHOLD WILL BE SAVED.’ 15 And as I began to speak, the Holy Spirit fell upon them, as upon us at the beginning. 16 Then I remembered the word of the Lord, how He said, ‘John indeed baptized with water, but you shall be baptized with the Holy Spirit.’ 17 If therefore God gave them the same gift as He gave us when we believed on the Lord Jesus Christ, who was I that I could withstand God?” 18 When they heard these things they became silent; and they glorified God, saying, “Then God has also granted to the Gentiles repentance to life.”
