Uncertainty about what is going to happen to us always makes us feel uneasy. If you know that some evil might materialize to crush you, you begin to experience what the Lord must have felt when he went through the agony in the garden. This would be the perfect time to get on your knees and abandon yourself entirely to God until you feel the deep union between you and him. So uncertainties are blessings. And, you know what, God always shields and delivers you from evil and restores your peace at the end.
