Praise in times of trial

The book of Tobit reveals the secret to holiness and deliverance: praise and confidence in times of trials.  No matter how sad, how beaten you are,  praise to your God and have confidence in His goodness and sovereignty.  Tobit and Sarah were each so grieved as to consider life not worth living, yet even then they turned to God with confidence, submitting to His will.  At the moment they prayed they were heard by God, who sent an angel from His court to heal them even before they had left their places of prayer (Tobit 3).
