Grab yourself a Psalm

When Jesus was on the cross he cried out: "My God, My God, why have you forsake me?"  Many people have asked why he would ever think that God the Father had forsaken him.  But Jesus was actually reciting the first line of Psalm 22 - and many people have suggested that by saying that one line, he was in effect invoking the entire Psalm, which happens to end with an affirmation of God's commitment to always come to our need.  Indeed, those standing around the cross are likely to have been familiar with the Psalm if they knew Jesus.  We look at several Psalms and consider this question: When we are in need, when we are in crisis, should we do what Jesus did and grab a Psalm?
