All have sinned and fall short of the glory of God (Romans 3:23)
Those who sin will not inherit the kingdom of God (1 Corinthians 6:9-10, Galatians 5:19-21)
Jesus came to save sinners. (1 Timothy 1:15)
Jesus offers cleansing from sin for those who:
Believe in Jesus (John 3:16)
Confess their sin (1 John 1:9)
Repent (Mark 1:15, Luke 13:3 Acts 3:19, Acts 9:22, 2 Corinthians 7:10)
Live holy, free from willful sin (Luke 10:25-37, Matthew 25:31-46, 1 Corinthians 6:9-10, Galatians 5:19-21, 1 John 2:3-4, 1 John 3:7-8)
Endure till the end (Ezekiel 18:24, Matthew 24:13, James 1:12)
On judgement day, you will be judged according to what you have done (Revelation 20:12-13, 2 Corinthians 5:10)
He who does what is right is righteous because God forgives those who confess and repent of all sin. (1 John 1:9, 1 John 3:7-8, Ezkeiel 18:4-9, 20-31)
Those who sin will not inherit the kingdom of God. (Revelation 21:8, Matthew 25:31-46, 1 Corinthians 6:9-10, Galatians 5:19-21)
Willful sin is not an automatic outcome, but a choice. There’s always an escape from sin. (1 Corinthians 10:13) God does not command us to do something that we are not capable of. (1 John 5:3, Deuteronomy 30:19-20) Many in the bible were described as righteous, perfect, obedient, and pure in conscience. (Genesis 6:5-9, Job 1:1, 1 Kings 15:5, Ezekiel 14:13-14, Luke 1:5-6, Acts 23:1, 2 Timothy 1:3)
Man is not born a sinner with a sin nature. This curse is never put on Adam and Eve in Genesis 3 and is clearly wrong from scripture. (Ezekiel 18:1-20, Ecllesiasties 7:29) Sin is transgresion of the law which means in order to be a sinner you must transgress the law. (1 John 3:4) When life begins at conception, you don’t even have a brain yet. You wouldn’t be able to transgress the law and therefore could not be a sinner at birth.
Jesus did not transfer his righteousness to us and become sin for us. Sin and righteousness is something you do and can’t be transferred (1 John 3:4-5, 1 John 3:7-8, Ezekiel 18:20-24) Jesus death on the cross cleanses us from sins previously comitted. (Romans 3:25-26, 1 John 1:9)
