Let me offer my insight regarding the verse.vvart wrote:.
Check out this verse:
"Some are born without the ability to marry, and some are disabled by men, and some refuse to marry for the sake of the Kingdom of Heaven."
Matthew 19:12
"Some are born without the ability to marry" That is implying that mankind don't use their heart enough to feel one another, instead we're influenced by the environment to rely onto our eyes to see and judge.
Meaning relationships are base on attraction, and most attractions are base on how one sees another with their eyes. Their eyes blinded their purity to use their heart and feel one another. Everyone born differently, some are burn more physically attractive than another. Therefore those people may have trouble to marry because most people use their eyes to fall into attraction.
"and some are disabled by men"
That is implying that back in those days, boys are physically disabled "meaning they have their male sexual organ removed" also known as neutered. It's a common practice in China Empire.
"and some refuse to marry for the sake of the Kingdom of Heaven."
Those are the people chosen by God to serve for God.
To be the one you have to be by one. All attention and focus are dedicated to the cause in succeeding the mission. Which prevents any other form of energy and attention for a sustainable relationship such as marriage. Being in a relationship such as marriage takes huge commitment, it wouldn't be fair to your significant one if you can't dedicate all your energy and commit to them. In order to succeed and go far in life, sometimes you need to make sacrifice, and by sacrificing our desire to be with that special person, it balance out and allow us to fully dedicate everything into the cause and mission of serving for our Lord.
