A True Benediction

How does this praise and blessing to God comfort Christ’s people and cause them to say amen? How could a mere man have written such praise to God? How do we see that every Spiritual blessing comes from Christ alone? How and why is Christ able to keep His own until the end? Why should we be thankful that God is Sovereign? When a child of God falls is it forever? How is Christ both willing and able? How is Christ’s work perfect and why? What makes up a true benediction? What is it that the child of God awaits?
