Someone once told me it was okay to use copyrighted material inappropriately in order to promote Christian devotions. He said, "At the end of the day all that matters is that God is glorified."
He expressed a popular belief: The end justifies the means.
But does it?
Scripture offers these guidelines
1. Rahab lied to save the lives of the spies, and God rewarded her. So saving a life might require violating a lesser law of God.(1)
2. The Apostles refused to quit speaking about Jesus when the authorities ordered it (Acts 4:1-22). So we can/should disobey laws that prevent us from sharing Christ, although we do so at our own risk.
3. Romans 13:5 says, "it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience." A Christian's conscience should bother him when he disobeys laws without just cause.
God tests us in the little things (Luke 16:10) and we never glorify Him by cutting corners.(2)
(1) The Old Testament also allowed killing in self-defense. (Exodus 22:2)
(2) Using copyrighted material is a form of stealing. Following copyright laws doesn't prohibit us from sharing the Gospel.
For more on this subject, check out the devotion I guest wrote from my friend Dawn's blog. It's called "God Wins All Wrestling Matches" and talks about a time when I almost broke the law and when I did break the law.
