Sin is a given. You must budget for it. The way it ought to be dealt with it Biblically and quickly so that accounts are kept short and up to date.
Romans 13:8
Owe no man any thing, but to love one another:
for he that loveth another hath fulfilled the law.
Keeping the law by loving one another is the best way to stay healthy. No one should owe anyone anything except to love one another. That means no apologies should be outstanding and no forgiveness should be withheld.
Proverbs 3:27
Withhold not good from them to whom it is due,
when it is in the power of thine hand to do it.
Everyone is giving and receiving what they owe one another. This will keep the sniffles away.
Church discipline is good medicine. If you get sick, it's not the end of the world if you address it. If you tolerate viruses, you could die. If you eliminate them, you can live to fight another day.
Song of Solomon 2:15
Take us the foxes, the little foxes, that spoil the vines: for our vines have tender grapes.
Good fences make good neighbors. Do your best to keep the foxes out of the garden. If they get in, chase them out. Little things can ruin everything. Do not sleep on small sins. Set up good guard rails and keep the good well protected inside and the bad well defended against.
A fruitful vineyard is an attractive target for sly foxes, so the better the fruit, the more attacks you can expect, but the better the defense, the safer the garden. Do as Adam ought to have done and protect the garden. Do not allow snakes to slither about and do not force your people to face them alone or allow them to think that they aren't as dangerous as they really are.
