When Jesus met the woman at the well He told her He could satisfy the deepest thirst of her soul, and she would never thirst again, John 4:13-14.
Jesus is all we need for satisfaction. Only He can satisfy the soul. .
Psalm 107:8-9 Oh that men would praise the Lord for his goodness, and for his wonderful works to the children of men! For he satisfieth the longing soul, and filleth the hungry soul with goodness.
Jesus is all we need for salvation. All who believe in Him are promised eternal life in heaven. Anyone can be saved—any sin can be forgiven.
I have never met a Christian—one abiding in Jesus—feel that he/she lacked any good thing.
For those who abide in Jesus have found the sweet, cool, soul-satisfying goodness of God.
