In today's first reading from 1 Corinthians 4 at morning Mass, St. Paul said that when the Lord comes, he will bring to light what is hidden in darkness and will manifest the motives of our hearts, and then everyone will receive praise from God.
Anyone who truly trusts in God is not concerned about what is going to happen to him because he has left all in his hands. He is willing to accept whatever God sends his way ~ no questions, no complaints; only total acceptance. He welcomes God to expose all that's hidden in darkness and manifest the motives of his heart, for he knows that whatever he receives will be for the glory of God. When one abandons himself to God, all fears and worries are tossed out as well.
