Therefore I tell you, people will be forgiven of every sin and abusive word spoken [against God]. But abusive words spoken against the Holy Spirit will not be forgiven.
1 Corinthians 6:9-11
Or, do you not know that evil people will not possess God's kingdom? Do not be misled: neither will sexually immoral people, nor idolaters, nor those who are sexually unfaithful to their mates, nor homosexual perverts. [Note: The Greek uses two words here, denoting both the passive and active partners in male homosexual acts].
1 John 1:7
But, if we live in the light [of righteousness] just like God [constantly] lives in the light [of righteousness], we can truly share a relationship with one another and [can know that] the blood of Jesus, God's Son, continues to cleanse [our spirits] from all of our sins.
1 John 1:9
[But] if we confess our sins [to God], He is faithful [to His promise] and righteous [in His judgment], and will forgive us of those sins and cleanse us from all of our wrongdoing.
1 John 2:1-2
My little children [i.e., dear ones], I am writing this to you so that you will not sin anymore. But if anyone does sin, we have Someone to go to the Father on our behalf; it is Jesus Christ, the [only] righteous One.
