Christ is the light of the world. If you turn your back to hide from this light, you shall remain in darkness. But if you turn to this light to let it shine upon you, you will feel its warmth and gentleness and also the love and mercy of God. Reject this light in this life and you shall never see it again. Accept this light now and you are on your way to living eternally with God. It's that simple, so don't make it hard on yourself and on God.
