The reason why the Lord gives us relationships is so that we can be perfected in love. And the relationship that's the most effective, above all others, in doing this is the marriage covenant. So many people, who claim they're Christians, don't have the Spirit of Christ dwelling in them. That's why they're getting divorced and remarried at the same rate as unbelievers. Remarriage IS adultery. 

The Rapture is a Day of Judgement because it will reveal to the World who's now being perfected in love and who's not.God's love is ONLY being received and perfected in us when it's producing acts of kindness towards others. This is why a married couple, if they're being perfected in love, will never get divorced to marry other people! That this is now so common in the Church indicates that doctrines of demons are being preached from the pulpit.

"If we love one another, God abides in us, and His love has been perfected in us. By this we know that we abide in Him, and He in us, because He has given us of His Spirit...Love has been perfected among us in this: that we may have boldness in the Day of Judgement; because as He is, so are we in this world. There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love." [1 John 4:12,13,17,18]

The fear John is speaking of is only going to grip the hearts of those, on the Day of Judgment, who are not loving their spouses, their children and the brethren, in this order. For if the spouse is not loved, neither can the children and the brethren be loved. On the other hand, when the spouse is loved, the children and the brethren are also being loved as well. For the marriage covenant is like a fountain that pours out God's love into all the other relationships we're in. All those who love in this correct order truly love the Lord, and are being perfected in love.
