Husbands, love your wives, just as Christ also loved the church and gave Himself up for her, so that He might sanctify her, having cleansed her by the washing of water with the word, that He might present to Himself the church in all her glory, having no spot or wrinkle or any such thing; but that she would be holy and blameless. Ephesians 5:25–27, NASB
There are really only two groups of people in the world. There are those who are branches bearing fruit in the True Vine who is Christ, and then there are those who are either totally separate from the vine in their rejection of Gospel or are branches in the True Vine who bear no fruit. Those branches which bear fruit have been cleansed by the washing of water with the word by Christ. Their sins are forgiven. The other group has not been cleansed so remain in their sins even though they appear to be in the True Vine.
