We are fond of making plans. Thus, David wanted to build a Temple for the Lord, but through the prophet Nathan God refused. Instead, in God's way of doing things, David's son Solomon would build the Temple.
Similarly, on the mountain of the Transfiguration, Peter suggested building three booths, one for Jesus, one for Moses and one for Elijah. Again God refused, calling Peter to pay attention to Jesus: "This is my beloved Son in whom I am well pleased."
Saul of Tarsus persecuted the early Christians. Once again God intervened and refused this misguided human zeal and called Saul according to a different plan: the plan to save humanity in Jesus of Nazareth. Saul had rejected the idea of a crucified Messiah, but, as Paul the Apostle, he came to realize, as he says towards the end of the Letter to the Romans: This is only what the Scriptures had predicted and it is all part of the way the eternal God wants things to be.
While we must make plans, let us remember that "God alone is wisdom" and keep our eyes fixed on Jesus, the beloved Son of God.
Glory be to You, Father in Heaven, for giving us the grace and strength to live according to the Gospel and so proclaim Christ to the world.
