Tim Keller got me reading John Stott’s Commentary on Acts, and man I’m glad he did. This past week, I preached on the kingdom of God from Acts 1, and I was created encouraged and helped by the insight and commentary of Stott, especially on Christ’s ascension and the mandate to witness in the power of the Holy Spirit. Commenting on Acts 1:9-11, John Stott wrote:
“There was something fundamentally anomalous about their gazing up into the sky when they had been commissioned to go to the ends of the earth. It was the earth not the sky which was to be their preoccupation. Their calling was to be witnesses not stargazers. The vision they were to cultivate was not upwards in nostalgia to the heaven which had received Jesus, but outwards in compassion to the lost world which needed him. It is the same for us. Curiosity about heaven and its occupants, speculation about prophecy and its fulfillment, and obsession with ‘time and seasons’ – these are aberrations which distract us from our God-given mission. Christ will come personally, visibly, and gloriously. Of that we have been assured. Other details can wait. Meanwhile, we have work to do in the power of the Spirit” (The Message of Acts, 51).
It is not for us to know the times and seasons the Father has fixed by His authority. But it is for us to know the power of the Spirit in testifying to the life, death, and resurrection of Jesus in word and deed. Those longing for the return of Christ are not those with prophecy charts in their hands but the gospel on their lips.
