Some people think that the disciples were just nice and gentle and spreading the love like the hippies in the 60’s movement. Here is Peter, who spent 3 years following Jesus absolutely everywhere, filled with the Holy Spirit at Pentecost, bearing the fruit of the Holy Spirit and he says this to a new convert! Charles Wesley wrote a hymn called, “Gentle, Jesus meek and mild.” He is, but he’s also “Firey, Jesus bold and wild!”
I love Peter’s boldness. He stands up, in the power of the Holy Spirit and preaches an on-fire word!
