About light with substance:

John 8:12 When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life." (NIV)

When you have Christ in your heart, you have within you a being of pure light. Christ is the Light of the World. The light of Christ is a light of substance. The light of Christ has form and shape. In addition, the Light of the World is eternal beauty, glory, and love. Through Christ you cannot just touch infinite love but become infinite love. These realities of Christ become realities for you when you accept Him into your heart.

In spite of the burdens of this world, your heart can travel to His place within you at any time. In His light, you can cast aside your sinful self. Then, at any time, you can talk with Him and know He hears you. You can experience the substance of His light. You can experience His eternal beauty, glory, and love. When you seek the substance of Christ you will find His substance is love. When you seek Him you will find Him because He loves you. Christ came into the world so you would be able to carry His beauty, glory, and love within you forever.
