If you turn to the light, the shadow retreats backward, but if you turn against the light, the shadow—darkness— is in front of you.
… God is light; in him there is no darkness at all. 1 Jn 1:5
If you look toward God, who is light, darkness always backs away. On the contrary, if you turn your back on God, you cannot help but put darkness before you. The only way to escape from darkness is to look at God and come toward Him.
Everything is seen under the light; our sins and the way to go are clearly seen. In the light, we are not likely to overlook sins, stumble in darkness, nor wander in the dark, losing direction.
Let us look toward God always. Our God, who is the light of life and salvation, will illuminate the way to heaven for us.
