The gospel of Jesus Christ can be summed up in John 6:47-48, 47 I tell you the truth, he who believes has everlasting life. 48 I am the bread of life. When the Jews received manna in the desert from Moses, it was temporal; it satisfied their daily need for nourishment which kept them alive. But when Jesus gave his body as a sacrifice for all our sins, He gave us the bread that satisfies completely and gives us eternal life. We simply need to trust and obey Jesus in accepting Him as the perfect sacrifice for our imperfect lives and thus satisfying our needs through eternity.
