Knowing what the heavenly calling is will not make me heavenly. The twelve had the personal experience of what Christ was for over three years. They had seen Him go up to heaven the Magnet that had drawn their hearts had gone up there.
In thought and affection, they knew that heaven was now the scene for them. He, being the center of their hearts, their affections follow Him there.
How am I to get heavenly? Get firm hold of the fact that Christ has gone up into heaven and has not come back. What do I possess if I have not Christ? Where have I got Him? In heaven!
G. V. Wigram
