On one occasion, Jesus drove animals out of the temple because their owners were misusing them. His disciples, when they later thought about the event, realised that in doing so Jesus had fulfilled an Old Testament prediction which said about the Messiah that zeal for God’s house had eaten him up.
When we think about this description of Jesus, what ideas come to mind? One is that serving God was more important for Jesus than taking daily food. Or we could say that since we cannot live without food, so Jesus would not live without serving God.
In connection to this outlook of Jesus, we can ask when it began. The answer to the question is that it began in heaven before he was born on earth. There, in heaven, he was the eternal Son of God, and he possessed everything. Yet there was an action that he wanted to do most of all and that was to become a man and serve the heavenly Father. This is the main reason why he was born.
After he was born, he served his Heavenly Father zealously whether as a child, a teenager or an adult. One story is given about his eagerness to serve when he was twelve years old. On that occasion, Mary and Joseph imagined he was lost. But he was in the temple, speaking with the teachers there, because he was about his Father’s business.
The main way in which he served the Father while on earth was by going to the cross and paying the penalty for our sins. Today, he serves the Father by building his church, adding sinners to it as living stones. In both these activities, his zeal is obvious and amazing. He is constantly active and never gives less than his best.
