A world broken by sin produces horrible displays of both perversion and injustice. Christians must take the beautiful light of the gospel into dark places. Paul teaches that although life is dark, Jesus satisfies my thinking.
Life does not allow us to choose our struggles. You not only face challenges and struggles but must also do so without instructions, clues, or help. Jesus satisfies every aspect of life, and He additionally gives peace in times of challenge.
Hansel and Gretel relied on breadcrumbs to find their way home. The Christian journey does not operate that way, since we have not yet been to our final destination! Paul reminds us that since Jesus directs our steps we must simply follow the trail.
