Open the Mail-bag again, and produce the letter "V," from the story of the Hebrew Children, asking another child to hold the letter, standing next in line. The message from these three faithful boys is that God's children should stand together like three links in a chain. This gives strength stronger than iron. Good companionship is the need of boys today. Fall in with the right crowd. A minister of the gospel, who was appointed spiritual adviser to a boy about to be executed, asked him one day what was his first step downward, and he replied, "I fell in with the wrong crowd." The Hebrew Children were a crowd made good by God, and they went through the fire before they would bend their knees to the idols of the heathen land. God stands with such a crowd; one and two made four in God's table of numbers. He is always in the midst of them. Jesus said, "Where two or three are gathered together in my name, there am I in the midst of them." The king saw him and said, "He is like unto the Son of man," and this was the reason. Three boys were fire-proof saints, so the fire did them no hurt. Open the Mail-bag again and produce the letter "A." This you take from Psalms--open to the Twenty-third Psalm. This letter hand to another child and tell the message of the Psalm, God is the Shepherd of his people, and his sheep shall know no want. They shall find green pastures, which signifies fresh pastures. Still water, deep waters, and so an endless supply. Still water runs deep in the Twenty-third Psalm. Paths of righteousness open up before the soul, like the golden sunrise every morning. Evil cannot make afraid, no enemy can destroy. Goodness and mercy, like two faithful shepherd dogs, follow and protect in the rear till the house of the Lord lifts itself above the clouds of time, and the "forever with the Lord" comes at last to all who follow the Good Shepherd. This is the story of salvation from our enemies and the open door to the house of the Lord in heaven. At the first part of Matthew open again the Bible Mail-bag and take out the letter "T," and ask another child to hold it and take his place in line as before. Let this letter stand for the birth of Jesus, the Angels' glad song, and the sky's "Merry Christmas" to the Shepherd with its glad melody of Jesus now born among men, the Virgin's Son. This is the story of the Glory Song of Salvation. Open again the Bible Mail-bag at the resurrection and take out the letter "I," asking another child to take his place in line with this letter. This letter delivers the message of the resurrection of Christ. It is God's special-delivery letter that the last and latest news is that Christ is risen from the grave, and orders that all the bells of joy shall be rung and the message declared to all the people. Salvation has been accomplished, and the stone that was rolled away from the grave by an angel's hand, has become the keystone of our faith. This is the story of salvation from the grave.
