"God doesn't send his church into the political fray with a strut and an open mouth but with gentleness and courtesy—with a readiness to do good, to avoid quarrels, and to speak evil of no one.
Why gentleness and courtesy? Why such an unexpected posture? Paul follows with his reason:
For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another.(Titus 3: 3)
...Those who have been rescued by God's grace are to engage those who haven't with gentleness and courtesy and a readiness to do them good and not evil. We should be quick to remember that apart from God's saving work—and owing to no work of our own—we share in the same disobedient, enslaved foolishness."
