How can Christians be both sheep led to slaughter and conquerors?

Les explains that this book looks at everything in the light of eternity, giving believers the blessed assurance that regardless of what may happen, nothing can separate them from spending eternity with their Creator God. He highlights the seeming contradiction: the sheep going quietly down the alley to their death, yet conquerors. That is the analogy. We are led like sheep to the slaughter, but the next verse says we are conquerors. So believers need not mind being meek, quiet, or coming under persecution, and can do it without squealing like a hog, because in the end they will still be more than conquerors through the One who loved them. Les stresses that we cannot do this by the energy of the flesh; in ourselves we are nothing. Paul then says he is persuaded—totally convinced—and Les recalls King Agrippa in Acts saying, Almost Paul, you've persuaded me, though he doubts Agrippa ever believed.
