What Bible is your pastor reading?
“Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.” Ephesians 5:25-27
love continues and is perfected in heaven. Marriage is not.
You will not meet a girl and get married in heaven.
And if you were married, and then married again for whatever reason, you will not have 2 wives or 2 husbands in heaven.
Marriage is a earthly construct made for the purpose of creating societal units for the continuation of the species.
And the love you are told to have for your wife is not the “lust-type” love that we so often now associate with the reason for marriage, but the type of devotional love that Christ has for the church, and that you can have with people who are NOT your spouse as well.
