The power of the world, the realm controlled by Satan, was defeated when Jesus accepted his Father's will to go to the cross. He broke and defeated the power of sin and death through his own sacrificial death. He brought life and immortality to light. He ensured that death would not have the final say. So in the middle of sorrows and trials, we can take heart and have peace — not because things are easy, but because the hard things of this life are temporary and are preparing for us an eternal glory. Our peace is not in the absence of strife or troubles, but in Jesus and what he has done to make our future sure!
