When we invite Jesus into our hearts..he gives us eternal life. He tells us in Hebrews, “Never will I leave you; never will I forsake you.” We crave things of this world because we are sinful in our flesh but Jesus came to give us life. When we crave wisdom and knowledge from His word we will be full of the Spirit. We go on hungry when we fill the void in us with people, food, money, material things, etc… The things of this world will never satisfy our soul like the Lord will.
And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. John 6:35
