We all have different filters through which we see life. Is it what other people think about us? Is it memories of bad things that were done to us by people we trusted? The world will corrupt us if we are following its teachings. Trust in the future comes from the light given us by God. Light that can see through dark filters that prevent us from knowing joy. He will replace that darkness with light so we can be at full power. God does not go down into the darkness where we stubbornly continue in our sin. If we ask Him for His light, however, he will shine it on us so we can come to Him.
