People can have affection for animals. They can even love their rose bushes and flower gardens. They like being around them. They have relationships with their pet collies and bulldogs.
We also speak about having a marital relationship between spouses. You don’t want to marry your cat, but with the way marriage is being redefined in our new pagan society, who knows.
Jesus speaks in metaphors or analogies whenever He tells us about the heavenly kingdom. He tells us what it is like using terms that we understand here, because we have not experienced there. It is like a farmer who sowed seeds, or a housewife who lost a coin.
He speaks about heaven as like a wedding banquet. When Jesus speaks of Himself He calls Himself the bridegroom. His Church is His bride. He is coming for His bride. He says He has gone to prepare a place for us and will come back to take us there so that where He is we (His bride) can also be.
He says, from the beginning God made them male and female. It is for this reason that a man leaves his father and mother (Jesus left heaven) to join himself to his wife (to cleave unto his wife), and the two shall become one flesh.
The great physical delight the bride and groom take in one another is LIKE UNTO the spiritual delight Jesus takes in being united to His bride spiritually in heaven. The two become one taking delight in one another.
Beings that have different natures can not marry, become one. To marry simply means to be joined together. Jesus took on human nature. He raises us to divine nature.
Heaven is not simply being in a place. Here in this place we have cats, dogs, rabbits, trees, vegetables, minerals, water, humans and a variety of thousands of things and species of life.
A man can have relationships with his pets, the team of horses that pulls his wagon or plow every day. The cow he milks recognizes him. We can feed the squirrels in the park all here in this place.
We can not marry them. We have different natures. The relationship between God and His Church is like the relationship of spouses.
In heaven we are not God’s pets that He enjoys spending time with, playing fetch the stick with, being amused by, petting on the head and taking care of. In heaven we share with God an intimacy of life whose only earthly analogy is that of husband and wife.
I suppose that unless someone has experienced a successful loving marriage then this analogy god gives us can not help understand heaven. In any case, you can be in the same place as your dog, but you can’t marry it.
