My opinion is this can be in direct exposure to God's grace shining on a sinner. It can be like how a worm on the sidewalk will burn and be paralyzed by the UV rays of the sun, while those same rays can help a human's skin to make vitamin D for healthy skin and bones . . . if I remember correctly.
But if the worm is under some moist leaves, the worm can feed on nutrients from rotten leaves which still have some sun energy locked in them (from photosynthesis) for the worm to use for energy, somehow, but without being in personal relating and sharing with the sunshine. Maybe this is like how sinners might not be able to stand Jesus, but they benefit a little bit from how God gives them food, but it is used for selfish living, while they miss out on the personal and tender intimacy we can enjoy with God.
