Everyone has difficulties in relationships both on a personal level and within a group dynamic. We have either injured—or been injured by—someone and gone through the process of reconciling or being reconciled. Sin causes a break in relationships that need to be biblically restored. But not everything that is directed at us falls under this category. There are people and groups and forces actively working to willfully and purposely cause us to make permanent breaks with no intention of ever mending them. Like an extra-marital affair that has as its goal to break up a marriage so as to get a commitment to a new marriage, so there are people purposely attempting to seduce us from a right relationship with God to something else.
The repeated biblical teaching is that we are to work through issues that result from sin, but to be completely intolerant when identified as part of spiritual seduction. There is no “reconciliation” possible with those that have chosen to be an enemy of God and desire only for us to join their side. Whereas we’re to live among sinners so that we can influence others according to our visible relationship with Christ, we cannot abide those who actively attempt to influence us to the contrary.
