A gram of prevention is worth a kilogram of cure. Whilst the word of God gives us principles for conflict resolution, it also gives us a heap of principles on how to prevent the conflict in the first place.
If Christians would take heed to the importance of how they listen, how they talk, and the potential of their words to do harm, we would greatly minimise the opportunities where Satan can get an advantage of us.
2 Corinthians 2:11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.
Galatians 5:13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
Galatians 5:14 For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.
Galatians 5:15 But if ye bite and devour one another, take heed that ye be not consumed one of another.
Galatians 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
