And the glory and power that he saw swallowed up his fear and grief to such a degree that he was able to trust God, intimately , not theoretically but intimately trust that God pulls all things together in Jesus, despite all the evidence to the contrary and in Stephen's case there was plenty. It is easy to feel that way. The insanity can pile up. The evidence can become overwhelming. Some people choose not to look at it, they insolate themselves.
Some people just get drunk or stoned.
Some people go off into fantasy land. Some people hate and blame others. Some people just live in chronic despair. Most of us do some of each of those things at one time or another. But the Holy Spirit never stops preaching to us, drawing our attention to Jesus, encouraging us to look at Him giving us subtle visions of God's glory with Jesus standing at the right hand of power.
