There is no marriage in heaven

Interestingly, when a husband wants to leave a wife, he told her, there is no marriage in heaven.
So?

Sometimes we forget why there is a marriage in the first place.

Why God established the marriage covenant?

There is no marriage in heaven because the need for marriage is no longer needed in heaven.
We will neither be lonely or there is a need to pro-create.
There is no need to learn to be perfect because in heaven we are already in God's perfect love.

That is the reason why there is no marriage in heaven and not an excuse for a husband to leave his wife...
