Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. Galatians 6:7 (ESV)
Boundaries keep us from disrupting the law of sowing and reaping in other people’s lives. God allows us to reap what we sow, so that when we act in ungodly ways, the natural consequences will push us back to God. If we “save” others from those consequences, we short-circuit this process, and prevent them from learning the lesson God would have us learn. May God help us discern the difference between these natural consequences of sin and the testing of our faith that is intended to strengthen us.
