Far be it for Bono to inspire us to take God’s hand in this battle.
It is the Holy Spirit that takes our hand:
"May you be strengthened with all power, according to his glorious might, for all endurance and patience with joy, giving thanks to the Father, who has qualified you to share in the inheritance of the saints in light."
Colossians 1:11-12
God does not care for "celebrity." To Him, the poor old woman in Manila who gives away her own last meal, or the young man about to be murdered for his Christian faith in Syria are the real superstars.
However, we are all given gifts - spiritual and otherwise. Moreover, God puts us all in certain positions in life. Think back to many instances in your life where you were amazed at the convergence of events, and you though "coincidence?" I have. Opportunities are set by God. Bono is a very famous man, and he confessed that Christ is the Son of God.
Again, that encourages me. I believe he has been redeemed for some time now, but the Bible tells us the heavens themselves rejoice at every believer:
"In the same way, I tell you, there is rejoicing in the presence of the angels of God over one sinner who repents." Luke 15:10
Therefore, we should delight also.
