"If the grain of wheat dies, it bears much fruit"

Gospel Reading: John 12:20-33
Jesus described his approaching death on the cross as his “hour of glory” (John 12:23) when he would be “lifted up from the earth” and would “draw all men to himself” (John 12:32). Jesus saw his death on the cross as triumph over the powers of sin and darkness. Jesus drew an illustration of the “grain of wheat” to show how this principle works in God’s kingdom. Seeds cannot produce new life by themselves. They must first be planted in the earth before they can grow and produce fruit. What is the spiritual analogy which Jesus alludes to? Is this simply a veiled reference to his own impending death on the cross and resurrection? Or does Jesus have another kind of "death and rebirth" in mind for his disciples? Jesus, no doubt, had both meanings in mind. Jesus’ obedience and death on the cross obtain for us freedom and new life in the Holy Spirit. His cross frees us from the tyranny of sin and death and shows us the way of perfect love.
