But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing into everlasting life.   John 4:14

So shall my word be that goes forth out of my mouth; it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing for which I sent it.   Isaiah 55:11

And now these three remain: faith, hope & love. But the greatest of these is love.
1 Corinthians 13:13
