Two book ends

I saw two book ends that support a row of books on a book shelf. If one of the book ends puts too much pressure on the books then when one is pulled out the rest could topple over. Similarly, in relationships and partnerships, whether in love, fellowship or business, there needs to be equality. The Bible says, we need to be equally yoked (2 Corinthians 6:24-18). This implies having the same morals and spiritual values such as patience, integrity, honesty, unconditional love and giving etc.
