Scripture also says that nothing unclean may enter heaven.

Scriptures also says: "Do not call anything impure that God has made clean." Acts 10:15. Christ's sacrifice has made believers 'clean' before God.

[Elsiejay]

If Christ’s sacrifice has made believers “clean” in the sight of God, would it not be presumptive, even insulting and belittling the efficacy and purpose and efficacy of Christ’s sacrifice, for me to presume that those those saved have need of further appeals for mercy from me through my prayers? Did not Christ achieve objective redemption of all creation, a salvation subjectively conferred upon all that are granted a saving faith?

[Campion]

Scriptures also says: "Do not call anything impure that God has made clean." Acts 10:15.

That's in a totally different context.

Christ's sacrifice has made believers 'clean' before God.

You are not "clean" before God when you sin. If you were, there would be no point in repenting. In fact, repenting would itself be a sin.
