Jesus claims to be able to give us a never-ending source of life that will last forever, as He said to a woman getting water from a well,

"Everyone who drinks this water will be thirsty again, but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life."   (John 4:13-14 NIV)

In another passage, Jesus calls out to those who feel weighed down by burdens,

"Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light."   (Matthew 11:28-30 NIV)
